50" width limit plus SxS and UTV's are not allowed
First off, I'm not sure why someone tagged "UTV" above under vehicles allowed because there is a large sign when you go in that says "MX and ATV's ONLY - NO UTV's ALLOWED" (and they make no distinction between a UTV and SxS). Then to get in you must pass between a pair of concrete post that are only about 53" apart. Even if your 50" RZR SxS fits it's still not allowed according to the posted sign. It would be a great place for SxS if they ever decide to allow them.
As for MX and ATV's it's a great place to ride, LOTS of space with some terrain that is unique in places. Not much running water or mud and kinda dusty if it's been dry but still worth the trip if your machine meets the requirements.
