Building the amount of stuff I do, I get my wood from a sawmill. I mean, you just can't get sycamore 2x16's from lumber yard, and even if you could, they would be stupidly expensive. So I have to buy wood from a mill at least a year ahead of time and let it air dry.
I put in a 1300 bd ft order with a sawmill about an hour south of here near Prairie Du Rocher. This was in early June. I called owner tonight to see if the order was ready. He said he was going to saw this weekend. He said he had the red oak on hand, but with the heavy rains we'd been having the the first set of sycamore logs were somewhere down past Cairo (Illinois). It seems that when the Mississippi river went out of it's banks the logs were caught and floated away.
