Jeff - no worries. I was still quite new to the racing scene (I suppose I still am), and the few people I talked to afterwards basically said you shouldn't expect much courtesy. Given that we're trusting our lives to one another on the track, I had hoped that courtesy would be a pretty common quality. If it wasn't, then I wasn't interested in racing. Thankfully, I stuck around a bit longer and was able to see that our "meeting" was the exception rather than the rule.
But if you want to say hi, I'm #538 and I'll (hopefully) be at Cresson next month. In the middle of buying a house right now though, so that's not set in stone.
