What uses have you found for old corrugated plastic signs, such as after a political election.?

I use them to construct model buildings in HO gauge.

fashion them into a hat

Dart boards, packing material, etc.

For sale signs because I didn't like the election outcome .

You should be zero waste, our landfills are already full, our sewers are plugged up.... good job trying to find a way to recycle, I can only think of using it as a placemat or doormat whatever is thrown in our landfill now will end us
