Lived in Maine for 10 years back in the late 70's and 80's. Friendly's were all over the place, along with a local chain called Deering's. There are still quite a few Friendly's around, the closest to Ohio is Olean ,NY. They are still in New England, mostly. Friendly's was almost interchangeable with Perkin's, except their ice cream products were better than Perkin's, and Perkin's bakery was better than Friendly's. But in Maine, Deering's was much better, especially the ice cream, shakes, sundaes, etc.
