Yep. Especially since commifornia outlawed lead weights. I've still got probably 6-700lbs of old wheel weights and maybe a ton of ingots.
A good source for lead is sheets from the x-ray room in a hospital. For whatever reason I know several people who have been involved with remodels of hospitals and have 2' high stacks of warped 4'x4'x1/8" lead sheets stacked on pallets, which are have long been pressed into the ground as the pile of lead slowly makes it's way back to the earths mantle. I used to do the wheel weight scrounging thing, pick out the zinc, smelt it with sulfur, etc. till I found out about the hospital sheet guys and just traded beer for some sheets to melt. Way less work and it seems like it makes nicer castings, probably because I would miss a couple zinc wheel weights.
