I get a 20 cubic yard dump truck full of Alabama gray rock for about 800 bucks. I can get the same truckload of limestone in Illinois for about 150 bucks. Rock is expensive in the Panhandle, but I see a really good limestone mix that they are using on 87 as the underlayment before the blacktop, and that is more like Illinois limestone, but I have No idea where they get it. The Marrietta Corp has a rail depot where they drop the rock from the rail cars and a conveyor transfers it to huge piles. Total rip off. They also have the port which gets white limestone chips which looks good on a driveway when mixed with white sand, but again.....way too expensive. I have never seen red Alabama rock. I would call around, but it depends on the quantity.
