Building advice is often like garden advice, it applies to a region that is two climate zones farther north from where I live. I have been looking for a source of GPS board, but it doesn’t seem to be available here in North Georgia (climate zone 3), but is readily available up North. I am sure a building supply house can order it for me… if I order the minimum amount, which would be way more than I need. I can order 20 sheets from an online supplier, but the shipping is over $600, almost as much as the cost of the product.

do any readers here in the South have any suggestions?
