My workshop is in the basement. I keep the planes I am activly flying at the time in the garage during the flying season, and in the basement the remainder of the time. My basement is dry and conditioned, but the garage is not. Unfortunatly getting my planes to and from the basement requires a treck through the house as I do not have an outside basement access. I have found the trip through the house causes a lot more damage due to hanger rash than the heat and humidity may cause.
