I'm retired and have the time to learn how to repair my own bike. Anyone aware of any schooling in the florida area? Adult classes or whatever.

www.parktool.com has short schools periodically at LBS all over, including 15 shops
in Florida. These are well regarded. Most of the shops have web sites that may
give some info as to how often they run the school. Also a lot of shops have basic
maintenance classes independent of Park. Ask around. Steve
