I didn't have the patience to wade through that whole thread, and Swamp Rat's sanctimoniousness was irritating the hell out of me. I would like to commend pitohui's response to SR, calling him out as a leach. He/she is exactly right. Losers and users.
SW, the concept of a carpool is that each member TAKES TURNS driving. Not just one guy leaching off of everyone else. As they say, it's "unsustainable." Your acquaintances will begin to avoid you like the plague. Hope it's right before a hurricane. Really, really hope.
