I have been there, its a very nice park. The facility is split into two sections. They have 3 tracks (A, B, C), a pee-wee and 1 junior track on one side and then 2 longer trails on the other. They also have plenty of single track MC only trails.
Tracks: A, B & C are all fast and flow well. The only thing I didn't like were the trail crossings; they have a potential to be hazardous so if you see them STOP and LOOK. Personally, I had a blast on the junior track with my kids as the berms are banked very well, it was like railing every turn.
Trails: On the other side (D, E) are very nice too. Some very good hill climbs with easy outs, pretty views and not too many ruts. No mud to be found which is a good thing for sport ATV users IMHO.
