Pros:
This is my first time being in Arizona (visiting relatives) so I don't know of the disc golf history in Sierra Vista or Cochise County but I believe this is a dedicated disc golf only course and it's great that the P & R people have given this piece of land to the locals. Where I'm from we get the areas reserved for nefarious activities we'll call it and pieces of land under two feet of water nine months out of the year so that's fantastic, seems like a decent rapport with these guys, so good on whom ever leader(s) or club(s) is leading the local charge when it comes to disc golf related things. Enough of that though on to the course!
I found the distances easy enough on me (have some physical limitations that I didn't in the past, getting older sucks) that I felt like I had birdie and par chances throughout the entire course but not so easy that I was bored. I played at the short tees I believe? (the tee pads with the signs on them) I found some of the longer tees and you could make the course more challenging this way as long as it's not too busy, (more on this below) for the more advanced players. The design (more on this below as well) uses the trees/bushes? to make you throw many straight shots right up the gut of the fairway and punishes you for hyzering or anhyzering off too far, mastering the no fade putter/midrange throw is essential here which is a cool feature as it is fairly rare that courses do this and makes sure you can't get by with just learning a RHBH hyzer e.g. which a lot of course designers seem to do for some reason. Some baskets even have one of the trees/bushes (still not sure if these roughly 6 foot high things with branches are ha!) in your direct line and have to throw over with either a finish right or left; I would say the design doesn't necessarily favor any style of throw over any other, though I only played it once, maybe over time I would discover something else.
I find the carpet pads to do the trick just fine, and I've never really had a problem with carpet pads as long as they are not dug up and most of these are in alright condition. It seems like some have been removed probably due to wear and tear over time, making you throw from the sand which I didn't have a problem with. I think this is maybe the best place for carpet tees due to the lack of rain and humidity most of the year.
This may be the only course I've ever been to that doesn't have beer cans and cigarette butts lining the course so great job on that, you locals should be proud!
Cons:
Alright so this is where my 1.5 rating mostly comes into play and I explain the 'magic number problem which is one of my biggest pet peeves in disc golf course design. This course suffers from trying to jam in eighteen holes (the magic number) AND alt tees on a piece of property that just isn't large enough to accommodate it. That's why so many tee pads, fairways and putting areas overlap making it unplayable for more than like two groups at a time; I saw a flyer for weekly doubles here, this must be a nightmare of constantly watching for flying discs and yelling out fore so much that your throat gets sore (if it's not already from the dry heat). Too many times course designers go into a course with the magic number already in their head and have to get to that number instead of designing a course with an open mind and fitting in as many holes as the property would allow. This course could have been a great 9 or 11 or 13 hole course, I don't know the exact number but it could have been done without having to overlap and sacrifice space for each hole. You could have a hole with three tee pads, one at 250 another at 300 and another at 400 or whatever and be able to along side six other groups playing the course safely.
One of the other issues I had which also revolves around 'magic number' problems is that you step up the the tee pad and see 2--4 other baskets not knowing which one is yours. Being that I played this in August at around noon in the desert (I'm an idiot yeah, big whoop wanna fight about it?!) I sure as hell didn't want to walk out to find which one is the correct basket to throw to. After a while I figured out that the little yellow sign on the top of the basket is pointed towards the tee pad you are throwing to, that made it easier. Of course being a local this isn't a problem at all but for us 'course baggers' (and there are a lot of us on this site) it makes it a little bit more difficult but again if you get rid of the crossing fairways, teepads, and baskets this issue goes away.
Other Thoughts:
I had a really fun time in Sierra Vista visiting family and even a pretty good time playing this course despite the low rating given. It's great that there is a pocket of disc golfers in the area willing to play in the blistering sun and take pride in their course. I saw only one other person playing this course on a Saturday at noon, either it gets very little play or residents are smarter than I and go in the morning/evening. If this course is that under used then many of the cons I have discussed could be a non issue for you. I live in the Seattle area where at Saturday at noon you wait 10-15 minutes per tee pad so this was nice.
