I use their wood and it’s excellent.Call The Woodshed. Good people, successful BBQ competitors, quality products that I’ve enjoyed using, located in Orange County CA. They carry post oak.

I've used Fruita, they're a good source too.When possible, I prefer to purchase naturally seasoned wood from Sharpe’s, Fruita etc.
My ace has had it before, but they didn't have it the other day.Here in Maryland, my Ace Hardware is where I go for Post Oak - by B & B. Home Depot has a pretty good selection of wood, but they don't carry post oak.
