200 miles aint bad. I drove my daily/track car 172 miles yesterday at 7AM for an event from 12PM-4PM, then 172 miles back, just to burn one set of tires. It cost me a full tank of gas and the gate fee, but hey if you enjoy the sport you'll suck it up. And I go to that event once a month, along with a more local one once a month as well. And you can ride along with some really good drivers, meet people, practice in a more controlled environment. Plus, at least around where I'm at, there aren't any turns you can hit speeds like this on:

Hope this motivates you to go legit.
