A very, very tall bike (without the biblical fire play). Nonchalantly riding to work, soaking up the smiles and cries of wonder, was a fellow who kept biffing his bike helmet on the overhanging trees. At the lights (he had to cling onto the traffic light pole to stay upright) I asked if he was the same fellow I see riding a unicycle down the roadside bike paths, and he replied that he wasn't, but that fellow was probably a member of his group, the exotic sounding Rat Patrol. Apparently they take old bikes and make them into strange and wonderful new
A bit further down the bike path there was an Asian student tripping along on very odd wedge heels that made her look like she was about to fall on her face. She just happened to have her camera out, and struggled mightily to take a photo and stay upright, with a very cross expression on her face. It's moments like these that make freezing your nose off worthwhile. Of course, I didn't have my camera with me. But I have the website now, and that will keep me amused for ooooh, five minutes.
If you like weird and wonderful bikes, or even if you just like tinkering with machines, check out the Rat Patrol. It's a US site, but if you follow the links, there's an Australian chapter with a Canberra branch. Steev, if you're reading, they also have a section of photos of dead bikes, right up your cycle-of-death alley.
