I raced back in the mid 70's and was basically car free. One of the guys on the team had a SubUrban that we used to haul everybody and their crap to the races. Did quite a few centuries at that time too. Don't do the charity rides, tried one and did not like the crowds and the number of ill informed riders. Still do the occasional vintage event or social ride as long as they aren't too big. Considered the Randonneurs but don't have the time to devote to it at this time in my life. Not car free either unless you consider I only own a truck, and only drive it for work
