I've been stacking wood all my life, Dad had a firewood business and taught me young!

We used wood pallets to stack wood on. Lay down a couple of well placed bricks, line up the pallets and your wood is safely off the ground with a little airflow to boot!

I've learned many lessons the hard way. That's OK, sometimes that's the way it goes. But not seeking out wisdom from more experienced people is the true mistake.
