I second Chas. I recently got a pickup truck load (1 ton) of 1 1/2" drain rock from Puna Rock, and can echo his observations. Really nice finish, durable as all get out, drive on it, no sand to wash away or end up tracking into house, but extra hard to shovel, though not impossible. I used it for a walking path and outdoor lanai pad over the bigger "trip you up" rocks that were all over from the bulldozer.
First step in developing a lot I picked up down in Kalapana is gonna be 20 tons of Sanford's 1 1/2" rock delivered and spread by "Rossome."
