Pros:
Great area, usually not crowded, very very nice course for beginners to get used to playing and learning how to throw their discs, some holes are very well designed and thought out, offers a fair challenge, some of the hole are excellent.
Cons:
Not cleaned out often (beers cans are frequently seen around the tees), lots of bugs... probably has to do with the standing water and mud on a few holes. Floods with lots of rain.
Other Thoughts:
This was my first course, and I found it extremely fun and challenging at times. For more advanced players its probably a little easy, but still great fun. The only major annoyance was the flooding. First hole was underwater and when you're standing on the tee you can't really tell. Its best to check it out before hand.
I recently played this course and the grass was freshly mowed and what a difference it makes! Holes 5, 7, 8 and 9 are MUCH more enjoyable and open. When the grass is long these can be a pain. With the grass mowed this course is a 4 out of 5. Overall, even with the tall grass, Barre is still a very fun course which I recommend.
