I think my record was number 5 to land, there were two on final 1 on base, another ahead of me in the downwind.
It's not all cessnas either. I've taken off behind a helicopter, and landed behind a jet (Think it was a gulfstream or learjet - following that thing in the circuit was scary).
That is partially the reason why I'm trying to find someone to host the feed for that airport. It's always active, with a wide variety of aircraft buzzing around. Not to mention the fact that there seems to be quite a few people in these forums that live around, or fly out of that airport.
