Oh man, you lucky dog. I'd love to catch that race! I've never shot F1 before or been to a race for that matter.
Indy racing is coming to my home town in June, that's as close as I'll get (I know, it doesn't count).
I've been to Indy multiple times for the 500. Best times to go are on Carburation Day and practice sessions, that is when you get the best access. Come race day you just have to have the right seats I guess (or be one of the chosen ones).
Share some shots when it's all over!
