We live south of DC and I have a 13yo that wants to get into competitive karting. I would like to get him started with used equipment and since I would be at the track give it a try myself. So that's two used karts now. There is a new track going in in Thornburg VA (close to our house) that they say is scheduled to open 2015 but not sure they will be racing karts there this year.
I am wondering a. what are the classes for a 13yo and old guy? b. good source of used equipment. c. what tracks have kart racing in MD DC and VA? d. what don't I know that I don't know and how do I get to know what I don't know. Any help is much appreciated.
