One of my friends on the Hamtech mail list/IRC channel played his C-3 atop a trailer pulled by a recumbent bicycle in a St. Patrick's Day parade in Ottowa. Here's Martin Petersen and his Hammondcycle: http://www.mkp.net/stpats/
He powered his rig with a UPS...he got an hour and 40 minutes of playing time out of it, covering the duration of the parade.
Thought y'all would get a chuckle out of it..I sure did...pretty imaginative!
