Where can I find old aluminum road signs?

Looking to do some water-jet cutting for some kids toys and want to upcycle old aluminum signs... but I don't know where to find the signs.

Dumb question: Have you considered simply ordering sheet aluminum?

Your local highway department or county road department would have them but I don't know that they will part with them. They are probably already recycling them as aluminum has scrap value and most government agencies are cash strapped. Yep, fighting over the left overs.
you can usually find them if you just drive around and look... theyre typically on top of posts.
