When I lived in Orange County CA in the 80s, most players were switching bands frequently. Always trying for the magic combination, the big break. I think the longest I went was 2 1\2 years. Since I've been back in MD, I've spent 24 years in a band with my brother, 9 and 10 years with a couple of country bands, and 6 years with my current alt_country group so far.
