Well, it finally happened. I visited my Local Lionel Dealer yesterday, and found a big "CLOSING SALE" sign standing on the sidewalk outside. After I-don't-know-how-many years, the owner is retiring and closing his doors for good. It was a very good store, handling both postwar and modern Lionel, as well as MTH. I am going to miss both the shop and its owner, who was a fine guy.
Unlike most people here (apparently), I don't live in a metropolitan area, and the nearest other shop is over 45 miles away. As life's crises go, this one is pretty small stuff, of course. But having to use the internet from now on for each and every hobby purchase, sight unseen, is going to be a major pain for everyone who was a regular customer (and I know there were plenty).
Of course, the really bad part is how often this scenario is being played out all over the country, judging from the number of similar postings I've read on this forum.
