There are trails there from stock to extreme buggy, and you can view most all trails from a stockish 4x4 vehicle if its dry. During the Summer it can be very dusty and during the fall and spring it can be very wet.
There are usually a good group of people there every weekend to ride with. If your worried about the weather be sure to call ahead as sometimes he closes due to rain.
I highly recommend going there. It's the place that got just about everyone on this board into wheeling and has always been an awesome location to try out the rig or camp with some friends.
