Good shout. Forgot about the newly rejuvenated Blyton.
I too find it easy enough to talk to most at trackdays, it does tend to transcend badge snobbery. Last time I was at Goodwood I ended up in a bay next to, and spent most of the day queueing with and talking to a guy with a brand spanking new GTR which he bought solely for track days. Turns out he is a very wealthy individual with an Aventador on order...but he didn't stop asking me about the Clio!
Having said that, there's a new breed of trackday attendee that I don't get along with. They tend to turn up with beat up old E36 M3s on trailers, stripped out and covered with stickers and spoilers, and seemingly with a point to prove. Again, last time out at Goodwood I almost got rear ended by one in a braking zone, and the last session of the day was cancelled as another one put his over the tyre wall on his out lap.
