Ray,
You should call up there and ask about riding in nov, if there is no snow, they probably won't care. You could also ride, millstone hills, in barre. That place is awesome! You could also check out green mountain trails in Pittsfield, very sweet rides. I know you love the technical stuff, I've never ridden the Burke side of kingdom trails, so I'm not familiar with it, but the other side is not very technical. Perry hills in Waterbury, has some great stuff with more technical riding than the other places I've mentioned.
That area doesn't usually have significant snow cover in early nov.
