It's life. For years I used to go to a small hobby store, but went when the owners retired (to be honest, it tried to have a bit of everything, which meant, a tiny amount of things, so, whilst it inspired interest in new hobbies, it never had enough).
Another one I went to is being turned into apartments (but they moved nearby), and another went online when the owner sold up and went to live in the country in semi-retirement. The saddest was a huge one which closed after, oh, 50 years, because the idiots who ran the area began to charge around $8/hour to park, killing off the customers. They said it was to protect the enviroment, and we should go by bus not auto, and it wasn't to raise money. Well, they have gotten half their wish - we don't drive there anymore! Sorry, so upsetting, knowing how a large, popular LHS was killed by idiots.
Still, on a brighter note, I still have within a 30 minute drive two large general hobby stores, and four LHS, of which one specializes in plastic, one in railroads, and two in r/c (one them does no plastic, but has a good range of paint, glues, etc). So, not too bad!
