I decided that learning to play guitar would be a great retirement project, so I bought a Yamaha CG122 and am practicing daily.  Things are going well so far and I think I can actually learn to play.

Update:  I have been building and playing stick dulcimers as well as mountain dulcimers for a while.  It has been going quite well.  I even built some small ultra light stick dulcimers (7 oz.) to take backpacking and bike touring.
