Cartoon,
I agree it is very expensive, I went to this place called gokartracer which is down the road from my house about half a mile down...
Anyways the website is
http://www.gokartracer.com/ and the prices are "Race: $45. Each additional race $40.
The race session begins with 5 minutes of qualifying, then racers line up on a grid for a 15 minute race to cross the finish line first"
This is in USD and apparently there were some professionals that stopped by that race in Laguna Seca Raceway.. Its pretty fun to know that and they are rather powerful machines, its even a requirement to wear a full protection suit
