I opened my treasure chest of memories yesterday when I noticed the ad in the paper for “A Tuna Christmas.” I saw the play with one of my daughters several years ago. And a few years earlier two daughters and I got our first exposure to this tiny town where the “Lion’s Club is too liberal and the Patsy Cline never dies” when we went to “Greater Tuna.” Two actors create an eclectic array of characters, a lot of laughs, and a good memory.
