If anybody else was looking to join, the Wednesday 3/26 light test ride is postponed until the following Wednesday due to crappy weather. I probably wouldn't have been able to make it anyway.
Same time and place. 23rd and 1st at 7:30. It may not be quite dark then, but close enough to get started. Ride will be down the East Side Greenway, back and forth if necessary, and then I continue over the Manhattan Bridge.
I've got a CYO Premium dynamo, a Lezyne Super Drive, and a cheap Keygos Chinese single battery/LED torch.
