I hit a patch of greasy fat this morning at the corner of Smith and Dean in Brooklyn and hit the ground real fast. Luckily I wasn't going fast or turning and of course I was wearing my helmet though I didn't hit my head. A nice Verizon worker come over and helped me out, gave me bandaids and told me that a fat-rendering truck had made a pick-up about 15 minutes before. Also a motorcycle almost wiped-out on the same spot. I was able to ride to work and my bike seems OK but my right hand is kinda ****ed up and cut. I feel like there isn't much point in trying to do anything about it but please watch out in the city for these things, it's like hitting ice, same kind of accident, you hit the ground really quick!
