I found this guy's website a couple of years ago, and of course I did consider paying $50 US for some guy to pick up some trash, and post it to me, just for a taste (or should I say smell?) of New York. Now I'm going, I don't have to. I am perfectly capable of picking up my own trash now, thank you very much, and much to the horror of my traveling partners, I probably will. But if you want I'll bring you some back!
