doo you live near WI? cause if you do, skip barber has a school out at a road america. check it out if you want. I'm going to the one at Laguna Seca soon... how does 500 HP viper or open wheel lightweight racecar going down the corksrew sound??!! :P http://www.skipbarber.com
or if you want there is a great school in Arizona, Bob Bondurant http://www.bondurant.com/
Bondurant is the best for beginers because they have the skid car, which simulates skids at the descision of the instructor. Much better than just going fast in water. Check that out too.
Hope this helps!!
