The problem is that in the northeast the rock has to be overhanging in order to stay dry. And you'll have to go party with the Abercrombie-clad climbers of the Gunks to find overhanging 5.8's.
Bring all of those old leaver-biners to the only rock worth climbing on cold winter days. Sunny, south-facing Sundown and Rumney. Climb until your arms give out or your fingers go numb, and when spring rolls around, maybe you'll be climbing harder than you were this past fall.
If it is sunny enough to climb on the South Buttress, it is usually warm enough to melt snow. So you'll probably end up having to hop over water streaks.
I live in the heart of the White Mountains, so myself and most people around the area find it hard to justify going south to climb trap rock (aka, crap rock) if i ever go down there, i will only be bringing one piece of gear (a #11 hex) to see if i can find a good placement when it KLANKS off the skull of your southern new england, bolt-chopping, pissed-off, self promoting, never-amounted-to-anything, climber. All of you CT climbers know who i'm talking about! He and the rock are the two reasons that CT will NEVER be a destination, even in the winter.
