Or, maybe those horror stories are from those with low alcohol tolerance lol
I knew I had picked the wrong college to go to... crap!
I don't think that there's anything about Mexico that makes people drink more there. The Americans and Canadians I've seen on vacation there chose how much to drink, and for some of them it was a bit too much.
I think some people get careless while on vacation and sometimes bad things happen because of that.
