might I suggest a banjo ukulele

It's way smaller & lighter than a banjo, but has the same sound! Also there are only 4 strings so it's easy to learn! it is cute though, you'll have a hard time frightening Eddie Bauer hikers with it
I'm bringing a regular ukulele. My boyfried plays harmonica so we're gonna rock out! And if I get tired of carrying the uke I might take up harmonica myself
