People act like pallets are junk(wood) not so . They will keep firewood off the ground and dry. Also pretty damn simple to reduce one to keep the wood stove warming your shop after they are shot. Mb
I get retired ones for exactly this purpose.
And added one one at either end of the small outside pile to support a cover that keeps the pine duff out as that stuff just holds water and defeats the purpose of getting them off the ground.
