Trent,

Thanks for your help. 6 to 8 lbs sounds like a lot per SF. Sounds like (at 7 lbs/SF) I need about 152,000+ lbs. So I need like 76 tons, or roughly $21K worth.

I haven't bought the 2 1/2 acre lot yet. Figures that with all the clay in N TX, I found about the only spot that doesn't have any. Maybe I should shop around for more clay.

Thanks again,
Joe
