I used to live in Valatie and I do miss the quite and hilly roads in Columbia and Rensselaer counties. I will say this though, Rensselaer county seems to have more vicious dogs per square inch than any place I've ever ridden except Mississippi. Hope the dogs were at bay. I don't think you will have trouble doing a century in say Saratoga county, which is relatively flat, if you can do 56 miles of those hills.
