The Twin Lights Ride is Sept. 28.

Looks similar to the Harlem Valley but less climbing.
For instance the 75 mile ride has half the climbing than the HV.
They have a great comaprison chart so you can compare their rides:

Located in south Jersey, it's about a 1 hr drive from where i am in brooklyn
or a 45 minute ferry ride from lower manhattan.
If you enjoyed the Harlem Valley (minus the rain) I'm guessing you'll like this one.
