Hey David - my husband and I are trying to be aware. Nothing would surprise me. The son lives upstairs in a small apartment and has the required macho pitbull on a chain outside (which got loose and mildly attacked my german shepherd as I was walking him). It's the general redneck scenario with a bunch of cars in the frontyard, speeding up and down the road 95 mph on a piece of junk Ninja bike at 1:00 am, domestic disputes loud enough to wake the dead, etc.
Sounds like meth to me. I would call the cops at the first opportunity and tell them you think they are making meth.
