They actually just closed. The owners are trying to sell the property ($1mil).
The park used to be an old golf course. There are a few hills and "whoops", but nothing technical. It was free-reign out there to explore and make new trails.
There are a couple of developing mud bog areas, but it's been a bit too dry for that anyway.
I made it out there once. It was fun and well worth the 25 minute drive to get there. I was basically looking at it as an excuse to engage the 4wd.
