My big score was from a demolition skip next to the place I was working. They were gutting a restaurant prior to turning it into a Red Robin's. The whole place had been done in 3/4" luan (aka phillipine mahogany), stained deep red and lacquered.
I filled my little VW van 3 times over. I got a few glares from some of the guys on site, but nobody ever said "stop". I suspect the stuff was destined for landfill, so nobody really cared to much about the crazy dude in the big dumpster - as long as I didn't hurt myself and sue. I was in there crosscutting long pieces with a handsaw to fit them in my van - LOL ! I don't think I've got the stones to be that brazen anymore.
I made a lot of simple projects with stuff - all painted. There were enough nail holes that it wasn't worth cutting around them. I completely satisfied wifey's demands for more shelves - upstairs, downstairs and basement Gave some away too. I figure there was 150 - 200 bd ft altogether.
All the best,
