I was rollin around this almost empty parking lot in Old Montreal talking to my dispatcher on the radio (head kinked sideways as we all do) tryin to find an address. I'm rolling around in big circles for a few minutes as he tries to find out where my PU is. I end up near the back of the lot, he gives the good 411 just as I noticed the new shinny steel cable strung across the cement bouys to keep the cars off another lot. Just about wheel height, I panic jam the front brake (i'm on the radio), over I go, unclip and fall onto the cable and my bike. I end up almost strangling myself (nice 6inch mark for a week on my throat), and denting my top tube. All was accomplished at a walking pace.
