I would suggest getting some small mylar bags for carrying some tobacco around. I would think they would maintain the moisture level adequately. I live in Indiana and understand the humidity thing. Since I prefer my tobacco rather dry, I'd rather solve your problem than the one here. I used to travel to Southern CA rather often, never had the experience Cosmic did. I once spent 5 days at the Broadmoor in Colorado Springs, the thin air had me a bit nauseous around the 4th day.
