Tom & other racers:

Does PCA allow depleted uranium as ballast? I saw this in a NASA email.
Note to self - don't stand next to a NASA car, esp if it glows.

15.20 Ballast
All ballast shall be solid metal such as steel, lead, or depleted uranium, and consist of a minimum of five (5) pounds per piece. Each piece shall be bolted in place with through-bolts, fender washers, and a locking-nut / system (e.g. jam-nuts, Nylock, etc.). All ballast shall be secured sufficiently, and all bolts shall be of grade five (5). Nylock nuts or metal crimping lock nuts should not be reused.
