There were parties all over Madame G's as well. I counted 4 simultaneous rope teams at one point. Which on a (one or) two pitch route, makes for some interesting traffic issues!
But everyone seemed polite and just too happy to be out on a great day. Too bad it can't be like that all summer. The difference could also be that it is the most serious climbers that rush to get their season underway in March, and these folks generally have a good handle on behavior and climbing etiquette.
