Mid-conference bike ride

  Since I live nearby, I snuck out after 1/2 hour of talk about advertising on blogs, which was very interesting (no sarcasm) but got rather detailed. As I was sitting there I was thinking that I probably could use the time better on my bike, so I got on my wheels and rode crosstown then uptown.
  Big headwind on the way up, so that's where I got my workout. Took a really nice video of NYers out on the trail at the usual turnaround point, just north of the 79th St boat basin.
  Big tailwind on the way back, so smooth ride. Feel great. The conference resumes at 2:30, just enough time for me to have a snack before heading back. Funny how it doesn't make a diff whether it's headwind or tailwind or nowind, my rate on the trail is betw 10.5 and 12.5 mph.
