Paragon has lots of dirrerant terrain. Deffinately put your skids on, many of the trails have large loose rocks from jeeps and trucks tearing them up. Some spots you can get a good amount of speed in, a few play areas with jumps and also some winding woods trails.
You can almost always go around the mud holes if you want, most aren't that bad unless the jeeps were spinning the tires to make some big ruts.
When you get there, you gotta watch a video for the rules, nothing out of the ordinary(helmet, me nice to others, take out your trash..)
Costs $25 for quads on weekends and they sell flags for $11.
Also, you can now camp there for $5 a night, never have, it's only 2hrs from me.
I would rate it an 8. Could be better if they cleaned up some of the rocks, but it's a great trip.
When do you plan on going? I might be able to get there.
