Pros:
My firebase this summer was near Boise and Ann Mo looked like the only noteworthy course. On Google Earth it looks like a placid park with open fairways, mature trees and an innocuous creek, so I brought 2 drivers, 2 mids and a putter and left my bag in Portland.
After 2 rounds both my drivers were gone.
The course, however, is a lot of fun, with the mostly open fairways letting you air it out, most of the lines playing straight with fades left or right to the basket, freewheeling locals who are happy to show you around, and just enough obstacles to keep things interesting. Grass is well-maintained and so dense that barefoot is wonderful in the summer[though damp in the morning, and Southern-humid midday], and discs rarely skip except in winter when the grass is brown and frosty. Baskets are excellent and moved often[at least 2 placements/hole], and there's a practice basket that collects some of the talented locals. There's enough shade on most tees or near baskets to not suffer too much on those 98+F days, and there's a giant fountain near # 11 that's excellent for temperature relief. Benches are everywhere, and during summer festivals often get moved far from the tee. Portapotties at #1 and bathrooms near #s 8/18, which is the ONLY place to get drinking water [!] in the whole park.
Cons:
Its the most popular course in Boise, so after 3 pm weekdays/ noon weekends it gets very crowded. And then there's the creek and ponds.
The creek is only 1-2 ft. deep and 6 ft. wide, but it moves slowly and instantly turns shit brown and reeks if you stir the silt up. The two waist-deep ponds that sideline #s 11-14 are almost always silty. In addition, waist-high grass and tule reeds line the creek 10 ft. to each side. I would estimate that on a busy Saturday, at least $1000 in plastic is lost here. At least two guys make a business of finding and reselling discs, and the local homeless have even gotten into recovering them for drinking cash. On #s 12-14 the Canada geese keep the fairways covered in fresh poop, which is what comprises the 1-2 ft. of silt in the ponds and creek[thus its stench when disturbed].
Trying to stay out of the creek and ponds will make you a better golfer, as they're in play on almost every hole. Wind is an occasional factor on #s 10-14.
Other Thoughts:
A couple of summer festivals put a two-day dent in regular play, but it only seemed to make a difference for a few hours or a few holes. An excellent library, Tablerock Brewery and Papa Joe's Coffee and Pizza[Sunday $2 Bloody Marys!] are all within 1/2 mile of the park. Boise Disc Golf is just south of the park on Vista.
