I fired off an email to the president, so hopefully he responds. They are right outside Richmond, so even if they wont ship to me my parents only live right up in Fredericksburg. Here's to hoping he'll sell me some
UPDATE: Wow, Bob called me back almost immediately. He's a suuuper nice guy. We talked everything from Lignum to engineering to VDOT. He says they have 20 tons of off-cuts for sale, which is sold by the pound. The unit cost is dependent on the size of the pieces selected. So I'll definitely be making a trip over to him next time I'm at my parents house! Huge thanks to Dave for telling us about this place.
