I wish I had a dime for everytime I've heard that question.    But it's the first one that popped into my mind when I saw these photos from my good buddy Marty.   Check this out, boys and girls!

Whatever it is, it's obvious there's a lot of work in this custom two-wheeler!  I'm wondering if those outrigger wheels retract, or if they stay down all the time...anyone know anything more about this mini-F-104?
