There's been a lot of buzz on the boards about queue etiquette lately, I really hope there are some official Disney folks reading. It seems like it is spoiling a lot of people's good time at the parks.
I can still remember going back in '71 and watching three teenage boys get thrown out for cutting in line at one of the "E" ticket rides-don't remember which one and everyone in line clapped. Haven't seen that kind of thing since.
