They're definitely out of season right now, but I'd still like to point out that they are exercises in futility. Hey, I'm all for people volunteering their time to help homeless druggies, but let me offer you a lesson in efficiency.

If you're going to build a house for left-handed, glue-huffing addicted, single mothers of inter-racial homosexual babies, why not build it next door? There is no need to travel to New York from Kansas, I'm sure somebody out of the 10 million will take your place. Save the money you would have spent on a ridiculously expensive airline ticket, and add another story to Uncle Charlie's home for the 1/8-crazed Albanian albino handicapped she-males. Thousands of college students are wasting their collective money by jaunting off to some remote location to help a disease ridden people who have recently been abandoned by their local college students who themselves have jaunted off to the hometown of the aforementioned college population, thus completing the cycle of futility.

You want to see the world and that's fine, but call it what it is, a vacation.
