Pros:
Rainbow City is an 18-hole course with a decent amount of challenge for the Rec to Intermediate disc golfer who has some control in the woods. Almost every hole has two decent-sized concrete tee pads and a DGA basket. I discovered, playing here for the first time, that the distances listed on DGCR were for basket positions that were, as of this writing, marked by PVC posts, and that the new basket positions are usually at least 50 feet further and often MUCH trickier. This provides the course with short and long tees and A and B pin positions for four different configurations (I played short tees to long pins). The disc golf course mostly occupies its own space in the woods beyond the parking lot in a nice community park with all the amenities (shelters, walking path around the perimeter, and sports fields in the front of the park).
Shot varieties included holes that faded right and left, sometimes incorporating the lake and often the winding creekbeds throughout. For most players, the signature hole here has to be #18, with a 200 foot water carry required off the short tee, but for me it has to be hole #3, with its pin position on a true island (peninsula), the basket being no more than 15 feet from the OB creek to the front AND 10 feet behind. They have installed a set of boards just behind the basket if you miss while running for the ace. I like the hole because I walked up to check out the "green" and wasn't sure I wanted to throw, risking having to fish my disc out of the cold (late December) water. I'm glad I decided to go for it (YOLO) - throwing my Buzz on a fade line, resulting in my first ace in six months!
Overall, the course has variety and is a fun stop if you're traveling I-59, and I'm sure the local community enjoys the course tremendously.
Cons:
We once went to the amusement park in Hershey, Pennsylvania, and saw a caution sign saying "You WILL get wet". Unless it's been dry for a looong time, there are eight to ten holes here which should bear that same warning. The water pools in marshy flats on more than half of the holes. About a third of the holes incorporate a tricky pin position very close to the six to ten foot wide creek, and three holes (1, 17, 18) give you a real chance to put one in the lake.
Speaking of #18, even though it's a signature hole, the long hyzer line (RHBH) flies right at the shelter by the lake (when I clipped the tree there, I wound up putting through the shelter - glad it was empty).
There are times when people walking the path meander into the inviting woods of the course near your lines of flight, so you may have to use caution (or wait).
The tee posts (by the short tees only) have only the hole number and no further information. The baskets are not, however, numbered at all. Although the course has many nice bridges, there needs to be one on hole #6. You currently need to circle around to the left, and double back unless by some chance you are athletic enough to leap the creek. The hyzer line for hole #7 fades directly over the long #8 tee.
Although some of the long tees appear to have benches, I don't remember seeing any by the short tees. I only saw two trash barrels along the length of the course. My overall takeaway from the course was that it's fun, but soggy.
