I was sitting around having a good conversation with a few friends about why we prefer solo and it got me to thinking. What's your drug of choice when it comes to competitive Motorsport? For me in my limited experience of drag racing, motorcycles, and now autocross. I much prefer the intense adrenaline rush that autocross provides. The cost involved with autocross isn't horrible either. I'm curious to see the responses to this thread. For those of you who compete in wheel to wheel how much is the price of admission? I find it interesting to see realistic numbers for cost between different levels of this sport.
