Rough cut lumber sources?

In the west almost all 2x12 construction lumber is made of Douglas fir, and I see train loads heading east so maybe it is available there. I use that on my cheese presses and only occasionally do I find a board with enough sap to be a problem.
When you find one it is obvious by looks and smell. You can buy kiln dried 2x6, but all 2x12 is not dried so you would have to air dry it.

East of the Rockies, at least, we use SYP for our 2x dimensional lumber.

Douglas fir is rare over here, and sold as a 'premium' product.

SYP is a very strong wood, but it's probably not easy to get out west because it comes from the southeast, with Georgia and Alabama being the largest producers, but especially Georgia.

This all comes from being a carpenter for many years.

Douglas fir is also not a fir, for the record, and should not be viewed as a substitute for fir in just about anything. If I remember, I think it is a species of pine.

Have you considered Tamarack---Eastern Larch--- it has no oder or taste----and the large stands are in the great lakes area----should be readily available and inexpensive.
