I was commuting to work on Friday, coming down a slight grade perhaps about 15 -20 mph, but not fast enough for the car behind me who was dogging my tail. I kindly pulled into the parking lane, no cars, to let him pass. The next few seconds proved a stark remainder as to why I generally never ride in the parking lane. One of the two adjacent restaurants, Thai, Mexican, had dumped cooking grease in the street. I'm not sure what passed through my mind while I lost traction; had a sense of sliding on ice. Unfortunately that sensation was short lived, ending when the pavement and I violently greeted one another. Most of the impact concentrated on my left hip/thigh. Hurt like hell!! As I looked up, I could see the car for which I had pulled over back up, I guess he came pretty close to running me over, and then slowly pull around me continuing his journey. This must be so common place as to elicit little concern from him. Somehow I was able to crawl to the sidewalk. A few pedestrians later, a kindly gentleman asked if he could help. He called 911 and 20 minutes later the paramedics arrived. Good thing I wasn't bleeding. Spent half the morning in the emergency room. X-rays showed no fractures and I was subsequently released. Today is Monday. Most of the left half of my body is a color best suited for plumbs with a patch or two or raspberries added to the mix.
