FENCE problems

I love shooting here at Irwindale Speedway, mainly because it never fails that pro or pro-am cars make it out to rip it up on the course. This time JTP ( Justin Pawlak ) came out with his FD car, fresh from the recent Seattle event. The only issue I ever have with coming here is the fact that I have to shoot behind a fence. Can someone please tell me how to get access to the infield with the rest of the photographers so I can try to get some better shots! lol I know its possible
