There appear to be largely two groups of people that take the train: old people and hot college boys. OK, there are probably some poor people on board, but nobody really cares about them. There are probably some hot sorority chicks as well, but (a) I am not really qualified to judge who is a "hot" sorority chick, and (b) Pffft, why wold I care about hot chicks anyway?
It really strikes me, though, how bimodal the age distribution is, though. (Yes, I'm a total geek.) There seem to be a large number of seniors, I assume because train tickets are much cheaper than airplane tickets and seniors are more likely to be on a fixed income. Cost is probably a big factor for the younger crowd, as well. There are very few middle-aged people here.
Don't get me wrong, I'm not complaining about the eye candy. I just wish that incredibly hot guy (hot in a cuddly-boyfriend sort of way, not in the underwear-model sort of way) hadn't gotten off at Reno.
