Depends on where the dumpsters are. There are upper scale condo buildings where tenants throw away lots of good stuff. I have found lots of interesting things myself when I take a look inside them. I picked out two HP laptops that were virus infected and restored them for my use(using one right now). Found a bag of 30 imitation name brand watches that worked. Found useful tools and lots of books. It can be endless. Oh, and there are the trash alleys at the shopping malls where lots of new things are thrown away by the stores.
