Alex Johnstone and David Rothstein run these pedal-powered coffee carts using local roasters' beans. At this writing, they had just received a cease-and-desist notice from a Southern California coffee company going by the Handlebar name (meanies!). Alex and David are still out there, though, and they're incredibly nice guys making great coffee—check out their Facebook to find them (it's still facebook.com/handlebarcoffee
for now... they'll be riding under a new name soon).
