More added for them will be nice!
1. Do not stack it against the house. The reasons vary but termites, bugs, and damp-rot are the main ones.
2. If you have to stack it near a wood fence, provide about a 12 inch free-zone between the fence and the wood stack (same issues as above)
3. By prefereance, stack it as far as you reasonably can from any wooden barns and from your house. In a residential area with smal lots, this may not be far, but try to get at least 20 feet from the house.
4. Raise the wood off the ground by 6 inches (more is fine). This can be done very cheaply by making a cinderblock raised area for those metal frames sold to keep wood, or can just be a long line of cinderblocks you stack the wood on. In a long term place with a farm, you'll possibly want to pour a cement bed for this.
Don and I just finished stacking 2 cords using a combination of the metal frames on cinderblocks, and just cinderblocks (have to get more frames next year). The frames let us get higher so save space, but the difference isnt all that notable with a little practice.
