For three Saturdays in August the city closes Park Avenue and connecting streets from the Brooklyn Bridge to Central Park and opens them to bikers, walkers and runners. Here's the map.

I did it two times last August and it was great! Gives you an idea of what the city might be like if we created places to ride without having to deal with cars. 

Tomorrow is one of those Saturdays. And the weather is forecast to be spectacularly nice. Not too hot, and clear. I'll be out on my bike. I'll be the nerd in the silver helmet. If you see me, say hello!  

Today's ride: 1 hour 7 minutes, 11.5 miles.
