What we've done is: screen dryer for screens, then stored in a dehumidified cabinet. We still have ink coming off of the film. I think you need a small room with a small AC, 5,000 BTU say, to keep stuff in on the worst days. I'm here in Mass too, and have dealt with this for a really long time now, and we still have troubles on the murkiest days. It doesn't last forever at least...
