Actually I think the attendees are down to earth (pardon the pun)....there is a great deal of sharing of equipment and information that goes on....one particular fellow has some spectacular set up and they all use it....I was around on one of the days after and there were stragglers (my moron of a dog went visiting so I drove over to pick him up -- he can walk there but then he's exhausted and I have to get him)...and I spoke with them...I picked up an extremely collegial atmosphere
