Man, if kart racers worried about paying an entry fee when they got to the track the racing world would be missing out on a talented pool of drivers.... If you hit big events your looking at $100 and up per class, and if you dont make the show you go home, no show money, no "B" main money, nothing. Plus instead of having 28-40 cars to worry about you may have 200, all as good as you or better, you get 6-12 laps of quals and if your not in the top 20 your done. An extra $20 isn't a big deal. Oh, and for us mid-western guys the close races were 6 hours away, up to 13-14 hours away. Some of the 12 hour drive races we went to we raced for a trophy... When we started racing sprint cars it was a bonus to not have an entry fee on top of a pit pass.
