Anyone now where i can get some lead ballast in the CA Delta area? Proflight no longer makes their's. They said that the price of lead is 3x higher than it was last year, so they don't make them anymore.
I tried the tire shop thing in the bay area and most of them have an arrangement with somebody to take it away. Try a metal recycler, I bought some 50lb bars from one in San Leandro for $25 each.
A number of people have reported success at getting old tire weights. I personally have had success cleaning up the debris from an indoor shooting range. Call and talk to the manager/owner. You will need to sneak in before they are offically open (you really don't want to be picking up lead during active target practice....)
