How about this for an idea? Pay to get in, take what you can carry, can go a second time, and a community event. This was a silent key sale. Of course not so easy for the moment. You won't get the full value of many things, but it is quick and easy. Perhaps give away after a couple of hours. Tony, the vintage radio fraternity is a large one, and a sale like this is especially encouraging to folk who are just starting up - there is little need for much to be dumped.
