Paul, I think any bidder owes you a reasonable explanation if they withdraw a bid. You may also notice that Ebay now records bid retractions on your feedback page. By the way, I don't think "I changed my mind" is a good reason and I would probably let the bidder know.

By the way, I drove by Citrus Heights two weeks ago when my son and I were on our way to Reno! Now I know where your new "digs" are!

Hope to see you at the convention!!
