Pros:
Easily the best course in the area. The SDGC has recently put up new bridges connecting the fairways on 2 and 17. The shrubs and brush have been cleared on the left side of 4... making it easier to find your lost drive. Most of the paths between the holes have been remarked using logs/branches.
TTP is a very challenging course, and it has a unique way of staying fresh for locals like myself who don't have many places to play. Five tee colors offer more than just different distances, but completely different lines to the basket. Many holes do not even share the same fairways from the the different tee pads. A day playing reds is completely different from playing blues for example.
The course itself is very wooded. Unless you've been playing for years and have your drive sighted in, expect to hit trees all day long. A handful of holes open up allowing you to rip it pretty hard, but some also bring water into play so throw cautiously.
Parking is plentiful right in front of the practice basket. Hole 1 starts a few yards from the practice area, and hole 18 ends a few yards in the other direction. Very flowing layout with not much walking between baskets.
UPDATE - Concrete teepads installed on every hole! Signage is excellent... and very helpful to find the correct tee pad/line for your tee color.
Cons:
Snakes! I'm not a fan of snakes and boy I've seen my share of them out here. Best thing to say is watch your step and make loud noises when your drive ricochets into the deep woods.
The water on hole 4 is deep... quick. If you lose your drive in the drink here, don't expect to get it back unless you dive in. While you're in there expect to find another dozen or so though.
There used to be a lot of trash cans around the course, but there weren't many out there the last time I played. I had to carry trash with me for quite a few holes before using the bin after 16. Due to this, you will see quite a bit of trash (cans, bottles) near the teepads of some holes.
People - TTP is a big park with lots of people visiting it every day. The pedestrian path weaves down the right side of hole 4. Also there is a playground right behind the basket on 18 that could potentially cause an interesting situation if your drive makes it back there. Also a gazebo near the teepad on 18 can attract kids who like to run around the fariways. Just watch out where you throw.
My only true gripe about TTP would be that because this is one of the few courses in the area, it attracts a lot of different types of golfers to play here. Most folks are friendly, but inevitably there are some that can be flat out rude. I regularly come across players out here who have absolutely no regard for families sharing the park with them. Please keep in mind that not everyone at this park plays disc golf, nor knows anything about the game. Be careful and watch out for kids near 1 and 18 in particular.
Other Thoughts:
In the summer, bring bug spray and a towel. Watch out for standing water after rain showers. Bring some bright color discs and have a blast!
