Today's DG Adventure

Today I had to go to the Texas/Mexico border for work (McAllen, TX). Prior to going, I coordinated with the local DG club in order to meet up and play their new course that plays on an old golf course.

I flew in this morning, did the work thing, and then met up with 4 guys to play a course that probably averages 350' per hole. We had a great time, and the course is going to turn into something amazing as it matures. I was able to share Vibram with a DG community that is relatively Vibram free (when I travel I try to bring a disc and leave it to the card/round winner as way was to say thanks for taking me around, and to share the rubber). The guy that won the disc was excited, and has been bragging about it to all his FB buddies in the local group.

The craziest part of the day though came when I got back to the airport in order to return to Houston. Since it was a one day trip, I only brought my DG bag, and a tablet on the plane. When I went through TSA on the return flight, my bag was flagged for something inside ("large round circular objects"). Part of the process included a pat down, and when they ran the pad through the computer, it started going nuts. Immediately everyone in TSA perked up, and about 6 agents came by and they all escorted me to a holding area where they stayed, and I got the super special TSA screening. I assume they thought I was a flight risk.

I fly a few times a month and have never had this happen to me so I was kind of interested in the process. (I wasn't too worried since I'm not a terrorist =p ). After about 20 minutes of going through my stuff, special screenings, etc. We had the chance to talk a lot about disc golf.

A few of the agents realized I wasn't a threat, and started asking a lot about it. One of them even said that the morning supervisor had been trying to organize an outside activity for the agents, and that disc golf was on their short list. They didn't know what it was, but they said after talking with me for so long that it sounded fun. The local DG club president knows a TSA agent, and has already put feelers out to try to make it happen.

When all is said and done, I'm now sitting on the plane, about to return to Houston. The positive substance that caused all of the drama was nitrogen, and apparently it was all over my pants and shoes when they scanned them. We all agreed that it was probably from the golf course fertilizer.

Thanks for sharing, that's awesome! :thmbup: :cool:
 
I guess your discs would have had nitrogen all over them, too. Good story!
 
Nice story -- TSA is funny, last time I flew out of LAX they waved me around the scanner -- I couldn't believe it, guess they thought I looked harmless but it made me wonder how often they do that.
 
I've been wondering about the status of that course in McAllen. There was some publicity on in last year and then things got very quiet. Is it open for public play, or ???

It is not on udisc or DGCR yet, but the locals play their regularly, and say they have permission from the city. Concrete tee pads on all but 2 holes (blue and gold tees), and great signage.
 
I don't know man, you have a beard. Clearly, that means you're probably a terrorist.
 
Wait...nitrogen? They screen for the main element in the atmosphere?
(I also shake my head at the tire advertisement that boasts of 'nitrogen inflation') :\
 
Interesting story, thanks for sharing!

Yeah, but terrorizing chains is different... isn't it?

There actually is a little something to using 100% N2 as opposed to air (78% N2, 21% O2, 1% C02 et al) to fill tires, but nothing worth spending $ on.

1) N2 is less "soluble" in rubber than O2, so 100% N2 stays in your tires longer than an N2/O2 mix, which means tire pressures will remain more stable over longer time.

2) N2 expands/contracts less with changes in temperature than O2, so tire pressure doesn't change as much when tires heat up due to intense driving conditions, longer highway trips, or very significant seasonal temp changes.

The advantages are more significant for racing than commuting, and while there's definitely some truth to the science, there more of a profit motive behind the marketing. :rolleyes:

As for TSA being concerned about the presence of nitrogen (which is abundant in most fertilizer), I can only assume it's because it can be combined with diesel or other fuel to create homemade bombs (recall the 1995 Oklahoma City bombing).

If Vibram discs are so great, why aren't you the round winner?


JK, I love my Vibram. You are doing the DG community a great service. Next time, take the train.

I was ;)

Ha, good point.

When they scan for "nitrogen", they're actually looking for nitrogen that's bonded in certain ways to other elements (probably carbon and hydrogen). It's just easier to say that they're scanning for nitrogen, compared to "scanning for certain types of compounds that contain nitrogen atoms" :)

The nitrogen that makes up the majority of the atmosphere is diatomic nitrogen gas (N2), which is very chemically inert. N2 gas is actually used in various industrial processes to prevent combustion/explosions.

Is that true? Per the ideal gas law, 02 and N2 should have the same sensitivity to different pressure/temperature/volume scenarios. I'd be interested to learn if there's an explanation for this that's outside the ideal gas assumptions.

A little googling suggests that N2 is a bit _more_ sensitive to temperature than O2 or air.

Not much more, ideal gas law and all, but 0.2% more sensitive.

Nitrogen is pretty common in explosives, at least historically - nitroglycern, TNT, nitro cellulose, etc. And I gather it's a pretty common target in explosive screening. But, I'm at the edge of my knowledge here.
