I did part of this ride mid-summer. I started from my place in Williamsburg and rode down to Coney Island via Ocean Parkway from Prospect Park. Then headed east until I caught up with the greenway. By the time I hit Frank Charles Memorial park I had used 2 CO2 cartridges and figured I should turn around and head home. I haven't been back as I "discovered" New Jersey soon after that and have spent most of my weekends over there instead but i may check it out again in the spring. What did you think?
