A couple three years back I saw a granite surfacing up for auction somewhere near Boston. The thing was 6 feet wide, 12 feet long and a couple of feet thick I think. I remember at the time thinking that it would have made an extraordinary glue-up surface. You needed a rigger to go get it (pickup only) but it never sold at something like a $1000 starting price. That would have been the mother-of-all-ScarySharp surfaces too.
