Well I was watching Magnum P.I....the old one...and they were all stranded on an uninhabited island...a military test site I believe...where they landed the chopper in an emergency...and their radio was picking up a drunken amateur broadcasting his rendition of, according to Higgins, Ukulele Lady written by Irving Berlin and some other guys. And it got me thinkin...if I was to have a leisurely life in Hawaii...where I hiked and biked and canoed around... fishing and hunting mongeese and wild chickens with my pellet gun....I think I'd choose a small bodied, fat necked, short scale uke with only a half dozen or 10 frets and fishing line for strings to pack around with me.
But...under my current, less leisurely lifestyle, where I'm not packing a uke around on my adventures, but instead may just play it on the couch or carry it around in my vehicle to play when it might strike my fancy, or on a car camping trip...with still the idea of traveling light in mind, I think I'd choose something that could not only be my only uke but possibly my only stringed instrument if it came to that. I'd definitely choose a 21" scale baritone with a 40-42mm nut.
