Yeah, I've heard of Freegans before.
It's something I could never do, though. Foodwise, at least.
I know most of the time, the food's not bad when they throw it out, but once it gets in that dumpster where there's other rotting food...naw, I couldn't do it.

I am thinking about dumpster diving for clothes though.
And my best friend's older sister used to go diving all the time, that's how she would have Christmas presents for everyone.
