I moved to the Franklin/Oil City PA area as a Browns fan in '74. Right up the street from the Steelers during their Super Bowl passage. Never felt like I fit in but I was in high school.
Yesterday I drove to the south east side of Pittsburgh for a car part and two old timers like me helped me load a used transmission into my RAV. They got a kick out of my mid 70's story and made me feel right at home. I don't know if it's the age thing or that they knew I was leaving shortly.
I think age helps.
I have 19 years in the North Canton area. It's my longest anywhere. The last ten I have been fiddling with cars daily and I feel somewhat that I am a local because of the networks I have developed. Many folks I meet "went to grade school" with another I know or dated his sister for a while. That sort of thing. Helps you feel grounded when you have mostly been a transient.
