I have 4 main piles. upstairs in the barn (which has fans for air circulation), downstairs in the barn (which has a dehumidifier), under the canopy next to the barn, and gets-wet-with-every-rain. most all of it is sorted into groups of like items (and by what sort of moisture it can handle), but I've never bothered to actually catalog them. I can't bring myself to catalog things I want to sell.
