I always stayed in and got the insurance pretty much every year since around 1970, but did the motorcycle, hot rod stuff for 2-5 year spurts. I see a lot of 50+ year olds coming back into it now that they have retired and have time. I think life gets in the way. Lots of young kids are out as fast as they are in. The Dune Buggy and car guys are even more fickle.
