In the next couple of weeks I want to erect a simple structure for storing my firewood in. I am thinking about sinking poles into the ground and framing a sloped roof over it. Being the frugal type I would like to spend as little as possible, I am wondering if ash would be suitable for the upright poles or would it rot quicker than say cedar. I have ash available on my property but if it wouldn't last I could scrounge some cedar at work. I am thinking of using aspenite (chipboard) for the roof cover with rolled roofing or shingles whichever I can get cheapest. I will be stacking the wood on pallets which I already have. Any input would be appreciated
