Pros:
Ber Juan Park is located right in Rolla, MO. The park is centered around a community center building, and a large pond behind it. Nine holes of disc golf play roughly in a clockwise loop behind the pond.
This is classic park golf. The holes range from moderately open with old growth tree trunks to work around, to a couple of wide open holes. There is nothing that I would call "tight", and no real rough to speak of. However, the aforementioned pond does come into play on several holes. Most significantly, #2 requires a short water carry across the corner of the pond. There are also nice rolling elevation changes throughout the course. My favorite hole was #6, which is a fun downhill throw at a basket in a little grove of trees.
There are two tee pads per hole. The pads are smallish, but concrete and in fine shape. The tee signs are also small and only appear at the short tees, but they have nice little maps and list all four possible distances (blue/red tees to A/B pin positions).
The baskets are Monkey Trap models painted orange. There is only one installed basket per hole, so there are two playable layouts at any given time. The pins were in the B position when I played. My impression was that most of the pin positions were just different, vs. being easier/harder. However, the tee pads are long and short so there is always a "long layout" and a "short layout". Neither layout is terribly lengthy or difficult, but it's a decent rec level challenge from the short tees and perhaps a moderate level from the long tees.
There is a practice basket that is pretty close to hole 1's fairway, but probably far enough off to the side to be out of harm's way. The park has trash cans, benches, and porta potties around.
Cons:
There aren't any Next Tee signs, so you'll need UDisc or the map uploaded here for navigation. Some tape in the basket rungs would go a long way here.
This is a multi use park and does have a few of the typical safety concerns seen with that type of layout. #4 plays near a parking lot, and a walking path could come into play on holes 6 and 7. Overall, I have definitely seen a lot worse in this regard.
The tee signs for holes 2 and 9 were missing as of my visit. And I'd like to see the signs at the long tees in addition to the shorts. I don't recall seeing an indication of which pin position is currently installed on those tee signs either.
I didn't see a kiosk.
