The trails are good for everyone. The tracks are a little advanced if you attempt to double anything. If you single all the jumps that would be a good thing to do.
Gomer thinks the "hard as concrete" dirt is a good thing however I prefer softer looser soil. Gomers concrete stuff is the same lap after lap and that's why he likes it, but if you fall on it.........Things get broken.
The kids track is fantastic and they were mixing sawdust into the dirt today to help soften it up.
My advice (from experience) is to SINGLE JUMP everything, be gentle on the gas out of the turns, and you'll be fine.........until you fall. :)
