Walking home from late night grocery shopping, What I first see as someone riding a 6-foot unicycle in the dark, turns out to be a man riding a tricked-out bicycle. Part of the frame of one bike is welded to another bike frame, making it twice the height of a normal bike. Adjustments have been made to the pedals and handlebars so that he can control pedal and steer from that unwieldy height.
A few weeks ago, someone threw some string onto across some bike racks, and posted a sign saying not to use it for the next 2 days because it was an art-project. Pretty lame art-project, I must say. Dadaism is boring.
