Pros:
I was actually quite surprised by the elevation and tightness of the treed lines used in this older, established, and heavily played, 18 hole disc golf course. It boasts long (about 12'x4'), level, concrete tee pads, benches pretty much throughout, good basic signage (that differs only occasionally from the map distances and angles: see below), and mostly rust-free spiderweb baskets (I really like this design: deep cages, three sets of chains).
There's a really nice shelter at the start (with a very small parking area), and a few sturdy bridges where absolutely needed to cross the creek. For tournaments, the roads and sidewalks are played as OB, which might come into play on holes 2, 4, 6, 7 & 18. The course plays around the entire park, with its hills, woods, low creek, and even a garden space in the middle, but does not seem to have any conflicting activities to cause safety issues for disc golf throws.
But the feature here is the variety of shot selection you'll need, and the brutally tight level of control you're going to need, especially on holes 12 through 18. Everything is reachable for even an Intermediate arm, but use maturity and self-restraint for the best results. I can visualize a smart, local player with the opportunity to play Crestmont several times a week just astonishing visitors with the number of deuces he could produce. It might also be a really fun course for doubles! And finally, there is a thriving Bloomington Club to tie into, if you live nearby (see 'other thoughts, below).
Cons:
Might just be personal preference, but I tired a little of backtracking uphill, and somewhat back up the fairways to tee off on holes 13 & 14, was perplexed at the lack of an entry into the woods to the terraced basket on 14. But mostly, I was a little shocked to see there were no landscaped steps in the hillsides on 15, 16 & 17. Those holes are very steep and look treacherous if really wet, so I thought it was odd not to see a course that's been playing up and down like that for decades, that didn't have these put in at some point over the years.
As mentioned above, the hole distances are pretty accurate on the hand-drawn map here on DGCR, and the concrete tees and signage are at the 'longs'. I only spotted one 'short' tee (a natural grass, toe-board tee on hole 6), but there might be a whole set of them, for all I know. They weren't flagged. One logistical note: when you play hole 8, the tee is oriented on the basket, which you can't quite see. Don't be disoriented by the map, which appears to angle the wrong way.
Finally, though I played during a nice dry spell, it was obvious that there are drainage creek crossing areas on holes 3 and 11 where you'll need to watch your footing if it is wet.
Other Thoughts:
I met Josh, TD'ing the 'Singularity' (one-disc) tournament the day I happened to stop in, right as they were finishing up. We talked about the fun they have with an indoor, winter, putting league. Josh's enthusiasm for the courses in the area that I happened to be trying out that day was infectious, but it was clear from him and from what I saw, that Crestmont is the place to visit if you only have time for one course while in town.
