Dave, I would check every boxed case of whiskey bottles..just to be sure you did not stumble on a motherload of product !!!! I bet when you first saw those pallets your heart jumped!
P.S. do you see other people there? Are there any security walk throughs? What does the local government do with it.....is it condemned property? I can't believe it can sit there....for years...without some kind of government action.
