Find the latest street junk, in real time

Map mashups are everywhere, but this one could have come only from New York City. And, unlike many others, it has universal appeal--and can even help tidy up the gritty streets of Gotham.

GarbageScout.com is a communal resource where people can submit locations of discarded objects, those charming fixtures of the urban landscape. The blog's motto says it all: "Found treasure map to New York City, a recycler's dream, a cheapskate's best friend, a dumpster diver's companion."
