Last time I did it on my Trek in late April I started at the Mass Park station and got as far as the downslope near the construction on the north side of the park - a small section of the new trail, just a sample. Really cool to see the Vanderbilt Parkway remnant, since it passes me where I live in Queens, near Cunningham Park. I'd love to see the reconstruction of the whole path as a MUP, as seen here: Motor Parkway Trail Vision Plan - Proposed Motor Parkway Trail
I do check your site periodically and will again. Thanks for that site, it has pointed me to some of my favorite rides!
