If you are truly in THE Raidernation, come on over to Nor-Cal Hobbies in Union City for some help. They have asphalt, carpet and two off-road tracks on site.
There is a both on-road and off-road racing tomorrow (Saturday). And, on the Memorial Day weekend (May 26-29), is the Reedy Road Race of Champions (on-road) featuring the best drivers from all over the world.
