This is a BMW touring bike with a sidecar drum set. Why? To rock while rolling. Actually I have no idea why, probably just because they could, which seems to be the only reason anybody does anything anymore. That, or to get high. *ahem* I'm looking at you, smoked banana peels -- you lied to me! I didn't feel anything except mushy stools for three days because I ate a dozen bananas in a sitting.
Thanks to bb, who has a beautiful voice and should probably get a megaphone installed in her car to sing to other commuters and bring some joy to their lives. That or to cuss at after getting cut off.
