I see people saying adults and what not shouldn't, but kids are OK. This is one of the few things that doesn't bother me because of my father. Those of you who think an adult shouldn't do it, but kids are OK because of bathroom breaks must have never met an older man who had prostate cancer and had it removed. When that happens, you can feel fine one minute, and have to pee like a racehorse the next, and their ain't no stopping it after about 5 minutes. 20 teens, yes,2-4 people, i don't really care. Kind of goes a long with the people who pass you in their car only to turn off soon after...realistically, its only gonna delay you 3-4 minutes tops.
