You mean there is something other than YellowWood in the South?
I have test used "lower price" Cedar and Cypress, the other woods avail here. I did not order in bulk cause they came in from the supplier at only 1/2 inch rather than a 5/8 or full board.
The cypress looked good in the beginning, but I dont like how it is weathering. It is turning black on the wood grain. looks like a bad stain.
Also, check the width as well, is it a 6 in board or or 5 3/4?
I have used the Chilean pine a ton. It is good.
