yes, lots of nice hilly riding in western Passaic/Sussex/Orange(NY) county, you can easily ride to Warwick via Upper Greenwood lake roads or via Sloatsburg which is by Ringwood State park. I do a lot of rides around there, (or really did, my road riding is very sporadic these days) but i still know the area well, growing up here and living in Morris County now. I know lots of nice centuries that can ride from Bloomingdale to Harriman State park and back that could be any mix of 17-100miles easily and much less traffic than Bergen County. I've ridden Pulis, 202, franklin and stuff, but usually at off-peak hours..

The Ramapo Rally (BTCNJ) they do in Sept will give you a great intro to riding in the western Passic, southern NY area... I've done the century there before.
