Goodwill pick

Our local Salvation Army has a dumpster outback, and I would occasionally stop to see if there was anything in it, (Scrap, Glasses, Resale) , and everytime I would go through there, there would be a mess. So I would stop, grab what I wanted from in the dumpster, then Id grab the push broom and scoop shovel I keep in my cab and clean up all the junk around the dumpster. But now there is a sign out back that basically says if you are caught on the property after hours , that you will be arrested, becasue of all the messes the other scrappers leave. It makes me sick that people are too lazy to clean up after them selves...
