I was riding home from work on the GW Parkway outside of DC when it happened. I had noticed some street sweepers further back down behind me on the parkway that looked like they were being put up for the day. I didn’t think much of it at the time. However, when I was starting down this long winding offramp I was going about 70mph. When all of a sudden I see this huge pile of muck (tree debris and wet soil mixed together) that one of the street cleaners must have dropped when they picked their brushes up to go around this bridge. I already had the bike leaned over and couldn’t change lanes because there was a Camry next to me and a car behind it. I couldn’t brake in time so I tried righting the bike to ride thru it. No dice. The bike slipped down on it’s side right away and I went sliding and tumbling about 200 feet, maybe further. The bike slid at speed into the guardrail and it did $11K in damages so the insurance company totaled the bike. My jacket did its job and was shredded. No upper body injuries. My jeans were shredded and my knee was hurt. Right after I stood up I could see the blood coming thru my jeans at the knee. Everything was fine but my knee – but the bike was gone. So I got myself a 2005 CBR 1000RR to replace it.
