Nope

I grew up

you're at the red, just walk 15 minutes further and ta'da, you're at another great piece of rock.

my guess is you were in Muir, at Bruise Bros. wall? Any place other than that and I agree they don't belong taking up a major crag if the kids can't even toprope the easiest climbs...they should stay secluded (and split up by 10 max) to Bruise, Practice and maybe Land Before Time areas. Big groups must learn etiquette somehow, so they gotta be told. If I spot them in the parking lot, I try to convince them of where to go and how to split big groups.
