This could really only happen in Boulder. From the Associated Press:
A Boulder man faced multiple charges including drunken driving and careless driving after allegedly stealing a street sweeper and taking it on a joy ride. Jeffrey Strom, 29, is also accused of aggravated motor vehicle theft following Monday’s incident. Street cleaner Callie Hayden, 25, told police she parked at a Boulder intersection and started walking away when she turned around and found the machine gone. Hayden said she quickly turned around and ran after the sweeper and watched as the driver did a few “donuts” in the street… …He reportedly admitted to officers that he drove the sweeper, but said he didn’t plan on stealing it.
