I just started scrapping less than a few weeks ago after cleaning out someone's garage and when I went to the dump to trash some leftovers I noticed people leaving stuff out next to the dumpster for the taking. Usually it's nicer stuff that people hate to throw out. I've scored some good stuff in a short time so far such as a boxing bag I sold for 20 bucks, gas cans sold for 5, antique gas can for 10 and even an awesome painting I'm going to get appraised.

Is this common at recycling centers/dumps in towns to leave stuff on the side of dumpsters that you can take or am I just lucky at my place?
