I would be interested in the Federal law, I'm in PA. I have had
restaurants say they must destroy the bottles each night, others are
more than happy to have you cart them away. I got well over 100 one
night form one local restaurant. The reason I was given for breaking
them was to keep vagrants from 'fishing' out the empties. It sounds
like a bit of overkill to me, but I have seen dumber things...
