Two years ago I had more firewood than would fit under my shed so I bought 2 PT 4x4x8's from Lowes, laid them on the ground, stacked the firewood on them, and covered the wood with a tarp. I just used the last of the wood (all good BTW) and went to move the 4x4's. They were eaten up and rotted from the ground side up. Termite tunnels were readily apparent. Two years on the ground, not in it, and they were completely useless! They still had the tags stapled on the ends so the staples didn't even have time to rust off. I knew it wouldn't last as long as the old PT lumber, but not even 2 years??
