I've been down there a couple times, but have only bought one sheet of 1/2" plywood to make shelving from. He has a lot of stuff down there and his inventory changes depending on what he finds a deal on and thinks he can make a decent profit on. I'm in awe of the huge slabs he has, mahogany & other exotic woods. His office desktop is made from one.
If you're gonna go, let me know & maybe we can schedule a meet-up there or do lunch, etc.
