My wife and I recently took a drive to San Diego, and on the return trip, stopped by the Namm museum of making music. A great place to visit if you are in the area. It is in Carlsbad CA, not far north of San Diego.

Great exhibit of some really cool instruments and music stuff. If you find yourself in the area, it's worth a stop.

I figured I'd spend 30 min or so there, ended up there for two and a half hours.
