where to buy ballast in WI

#1

Where can I buy lead weights for ballast near Appleton WI. I don’t want to know what shipping would cost if I find some online.

#2

I bought some lead bricks from McMaster Carr for my Miata build, but in hindsight it’s hard to beat second hand free-weight plates at Goodwill or Play It Again Sports. Drilling the lead blocks was a pain in the arse.
