Pros:
Wow, what a course! I had read about the terrain on DGCR and thought I would be prepared, but it can be really brutal in places. Parts of the back nine, when you are already tired, almost make you think the designers were as interested in wiping you out as they were in creating a great course (seriously? another #%@&ing stairway???). All in all, one of the best I have played in New England.
It is extreme disc golf, very focused on uphill and downhill shots, with only a few holes with less than 10' of elevation either way. Even #3, with technically 15' of elevation down, is a workout because the hole actually plays 50' down and 35' back up.
Many, many memorable holes, fun holes, extremely fair fairways, good opportunities for deuces and bogies, and I suppose a few 5s and 6s if you really get stuck.
The signage is perfect, showing you the line, elevation and distance at each tee and guiding you from one hole to the next tee, without overkill or ugly spraypainted arrows everywhere. I think most if not all of the baskets had high orange flags to mark their position, which came in very handy on a few.
Very little trash, just a few pieces of bottle glass here and there where some jerk must have thought throwing a bottle was a really cool thing to do, and might get him women.
All of the teepads were fine, some were awesome, some were just OK, but none were a trip hazard, and the couple that were OK I threw forehand and didn't need a run up anyway.
Speaking of forehand, I threw about 75/25 BH/FH, which I was not prepared for. I usually rely on anhyzer RHBHs to do the trick on left-right holes, but the fairways and tree placement on most of the left-right holes at Devens ruled out a sweeping anhyzer. Much better shot was a low, straight RHFH which faded right at the end. Seeing as I don't throw a lot of those, it was a little refreshing.
Elevation, elevation, elevation!!!! 30', 50' 70'!, 90'!!?!?!?! of elevation on holes under 400'?? And on some holes under 300'?????? Just awesome and a lot of fun.
Portable toilets down at the parking area.
This course is about 70 minutes from me, but I will definitely be back. Well done!!!
Cons:
Only three cons I can think of, all relatively minor:
1) Hole 9 finishes in the middle of the woods, so if you have to break for lunch (like I did), you have to walk quite a ways to get back to the car, then back to 10 to finish up. Not much of a con if you plan on playing 18 holes.
2) Due to the awesome and rugged terrain, your discs may take a beating, which may change your disc selection. There were a few times where I brought out a trusty favorite disc, thought about it, then put it back in and picked another with a slightly different shot in mind, because I didn't want to risk gouging a favorite disc. I often throw an SE Leopard, but never threw it once, although I had opportunities. So, if you are concerned about bashing your favorite Roc on one of the 17 million rocks on the course, leave it home. DX plastic will SUFFER!!
3) Some of the stairs and paths were in rough shape and, in a couple cases, were more dangerous than just clamboring down the hillsides. One stairway in particular (the really steep one on the back 9, #16 I think) had various missing chunks and exposed rebar supports and took some careful navigating to make it down. Honestly, that hole was worth it though.
Other Thoughts:
Bring water, really, really good solid shoes or hiking boots, and take your time. Don't throw your favorite 15 year old DX whatever unless you're looking to replace it.
There were a few missing amenities that you might find at higher-end or private courses (snack bar, tee brooms, bag hangers, etc), but I don't factor them in as Cons, just missing Pros.
