The lure to get into racing is great. Who doesn't want to rip and tear around a track with bumps and jumps?
Thanks to bill delong for putting things into perspective.
I always hated telling curious onlookers what it takes to get started. +1 for heading on down to track to talk to owner/operator of facility. They want newcomers just as bad as you want to test your skills on the track. Maybe they have a "run what you brung" class for people just starting out.
People don't always win because of their wallet size. Moderately priced gear, the right tires, and practice, practice, practice. That will go a long way to moving up in the ranks.
