My commute home included a stop at EMS for a new camelbak bladder for this Sunday's NYC Century. My old one had some stuff growing inside it that was resistant to anti-bacterial detergent. On the way home from EMS, I was following a motorcyclist who was squeezing between cars when he stopped suddenly. I hit the brakes and my rear tire flew up. Luckily I was on my feet when that happened. I heard the passenger in the taxi next to me say, "Whoa, cool!". The motorcyclist turned to look at me, saw I was right behind him, and promptly ignored me. The rest of the ride was uneventful.
