I dabble in lots of instruments. Mostly I'm a stringed instrument player (upright, acoustic bass, electric bass, guitar, mandolin), but I have a cajun button accordion. It's fun but very limited -- the singer in the house isn't fond of having to play everything in the same key. The Hayden system sounds versatile, relatively easy to learn, and thoroughly portable. I have a 120 bass piano accordion that is also amusing in small doses. Thanks for the map link -- maybe I messed it up, but it didn't show you in Redlands..
