*I'm so tired of re-tying tarps and replacing
tarps every couple of years has gotten old. *

I just buy the wood pile tarps from Mernards when they put them on
sale.
I cover the pile and then throw a couple of pieces of wood on top.
Never
had a problem and they last for 3-4 years b/4 they need to be
replaced.
Cheaper and easier than building a cover for the wood pile and it's
adjustable.
