I am going to stack my 2010 wood on pallets and have a couple questions. First, the ground is not level throughout the area I will be using. Is it OK if the pallets don't set level as long as you stack level or are you asking for trouble? Is it better to shim up each pallet so you are starting level? My first 4 are pretty good but then I start sloping up towards a pine tree. Do you wrap the wood with some kind of fencing/wire to keep them from tipping over or are some metal fence posts enough? Do you stack each row tight against its neighbor to avoid shifting and falling or still try to keep some air space between them to facilitate seasoning? Thanks!!
