The old town of Arcadia was established in 1886. Typical of towns at that time, it had shops, general and special stores, entertainment and necessities. Some of the original buildings are still standing, with most of them converted into antique shops. The most impressive was the Opera House. Now a museum and antique shop, it has a lot of the original items, including stage scenes, projectors, spotlights, and posters.
I had a photo of Barbara singing on the Opera House stage. I think she founded it and deleted it. Ah Ha, found it.
