Great course. Wide open enough for beginners, with enough challenging lines and hole positions for more experienced players who want to go for birdies.
Large rivers and ponds on the back of the course provide challenges. They are very slow moving though, so if you do throw a disc in, you dont have to chase after it.
Almost every hole has some sort of water/ob hazard, so it makes every shot interesting and provides a good challenge.
Huge concrete teepads and great signs showing the hole and all of the pin positions and lengths.
The parks and rec fellas rotate the hole positions (2-3 positions for every hole!) every 4-8 days, so it keeps the course from feeling stale.

Nothing major if you keep your disc out of trouble. The stream the runs through the back of the course is about waist high and is pretty gross to get into. Its pretty much stagnant goose-poo water, so make sure you take a good shower if you have to go in after a disc.
Don't throw your disk into the tall weeds. They are accompanied by a gross stinky swampy bog that eats discs!

Play in the morning to avoid crowds, but prepare to get your toes wet and run from sprinklers! Afternoons can get a little crowded. Overall a great course. I play it almost every day and it never gets old.
