Sounds good, thanks...pulling siding off the house? that's not dumpster diving...it's stealing....although I admit I have looked through the houses in the past for scrap wood.
Going in a house uninvited is a BIG No-NO.
If I catch someone in one of our houses uninvited they get to sit on the front step and wait for the police. YES we press charges. Good way to get shot too.
Too much theft going on to give any leeway. "I was just looking for scrap wood" is the first excuse given as they load your copper pipes and tools in their 82' datsun pick up.
Im always on high alert going into a vacant house. Had a face off years ago with 2 clowns who were "just looking for scrap". One had a pipe in his hands and all I had was a clipboard. Turned out ok but could have been bad.
