Not really. Just a guy with some common sense.
Pick anybody else taking those same 30 days off work, and chances are they're going to be enjoying themselves more than these kids.
As it happens, I'll probably overlap with them for the 30 days they're in the air. During which time I'll hike the Inca Trail, take a banana boat down the Amazon, and otherwise hitchike, surf and dirtbag my way from Peru northwards toward Columbia.
All for about the same amount of money.
So yeah, if you have a month to blow and a grand to do it with, you could certainly have a lot better time than these guys. That said, I wish them luck.
