Walt if you have any medical facilities in your area, such as hospitals, watch for remodeling operations especially if they have x-ray equipment. The rooms that hold this equipment have walls with pure lead lining them.
Also, if you know any repairmen who work for the phone company, plumbers or roofers, they many times have access to scrap lead.
I live in north Texas. If was a little closer to you, I'd try to get some to you as I have some extra. E-mail me at ggibbs@sbcglobal.net and maybe we can make some sort of arrangement someday.

P.S.- I used to live between Winnsboro and Mount Vernon. Isn't Cypress in that area?
