Pros:
Lovely, large farm environment. Mostly open and flat spaces, but has a few holes that involve trees and other vegetation. Some holes are at least visually (if not technically) varied. I do welcome the mild elevation at nos. 6, 8 long, 17 and 18. Holes 19 and 20 do mess up your traditional 18-hole mindset, but are good ways to end a round. Long hole 19 is a tunnel, particularly at the beginning (good challenge). No. 20 has a links feel to it; its short pad is also the no. 8 long pad. Definitely has a feel-good vibe, even though its basket is (also?) the practice basket. All in all, the course is a fun place to play, is not too busy, has scenic historical buildings (school, barns), etc. on a rolling, open plain.
Cons:
A bit remote in farm country north and east of Frederick, MD. Easy drive for locals, but off the beaten path for the rest of us. There is a walking path that is intertwined in many places with the disc golf course, so there is definite potential conflict with pedestrians, cyclists, and runners. You certainly need to be mindful and really look before you throw, especially driving or approaching at no. 3 and driving at no. 10. At both holes, there are bushes that obscure the walking path; a person could suddenly be in your line of fire. No. 19 is a par 3 from the red tee, but significantly long and narrow (should be par 4 IMHO; blue tee gets par 5 by comparison). Basket 20 appears to have been the original practice basket (maybe still is?), so there is some congregation around it. You might have to ask other players or other park users to clear the space to be able to play it safely. The hole signs don't tell you which tee is red or blue, but at least some of the time, there is also a red post or a blue post.
Other Thoughts:
A very pleasant place to play. I certainly recommend it for anyone coming this way or who lives in the area (latter, no doubt, already knows about it!). Probably good to pair it with Woodsboro (or some other course that's nearby) and make it a disc golf day trip for those coming from afar. If you come to the park on 15 North and then make a right on Old Frederick Road (or 15 South and then make a left on Old Frederick Road), you'll be making another right on DevilBliss Bridge Road. Your GPS might send you to the newish school that is across the street from the park. The park will be on your left coming this way on DevilBliss. Other activities in the park include baseball/softball, basketball, the aforementioned walking path, picnicking, playgrounds, football.
