Sure Wyo, but are you willing to stow it in the overhead when flying?

OK now here's another suggestion...and DON'T laugh at me. (well, not altogether anyway). Buy any cheap generic mandolin, remove the strings. Put only four back on. Tune them (from the bass) D,G,B,E. It will finger like a guitar and be lower in pitch, making it better to sing with. OK, NOW you can laugh...but I'm gonna try it tonight and see.
