After going to three Rockland Bike club rides, this was the first one that actually happened. There were about 15 people there. We split into two groups, and I went with the faster group. We climbed up onto 9W, then came back down into Tenafly (clockwise on the map below). I managed to stay with the ride leader and his speedy friend except for a couple spots on the hills. Thankfully, they waited for the rest of the group at the top of each hill.
It was pretty dark ridiing back, so fromnow on I'll be using lights on these rides.
Here's the map and profile. North is to the left:
