Cleaning out my inlaws house I picked up a 26' aluminum extension ladder. I thought I could store it under a deck, but it is too big and I really have no place to put it. Any harm to leaving it outside? We have a side of the house where no one ever goes and there are enough trees so the neighbors probably won't care. (They have never complained about the compost pile...)
I might use it every couple years, but when you need it, you need it.
