First, the ride to the east is truly dangerous. In one place I was riding up a two-way street that was about to turn one way (the other way). A cab enters the street on the wrong side, headed straight for me. I had to ditch between two cars.
Anywhere that you have to share a narrow street with cars is really dangerous. The moving cars cut real close to you, leaving you no option but to ride real close to the parked cars. And there's nothing you can do if a door opens into your path. I hate that kind of riding.
The actual riding on the bike paths, what little there is (compared to the west), is pretty good. But to the north there's a problem with the United Nations. They can't run a bike path through there, apparently. So the path just ends, with the UN in the distance, with the 59th St bridge beyond that. Today was a gorgeous day and a nice picture was possible.
The map for the day. 47 minutes. 6.65 miles.
