Some routes just don't work well with many people. TFJ is certainly one of them. I've heard people have turned around at the parking lot when they see the onslaught begin. Six on the easy routes up Hood, for instance, seems fine if not fun.
TFJ south and Washington n. ridge often seem to be peoples' first introduction to climbs of any real exposure. This seems to lead to unnecessary shouting about really being on belay, tangles, thrutching leading to rockfall, etc. Plus half the time it seems like the folks just met each other in the parking lot, so have no idea about each others' abilities.
