Strange Road Contraption in Milwaukee

I'm post-industrial spawn who has nothing better to do than be discombobulated at our industrial ancestors' creations.

Pavement Striper - Milwaukee

This strange little roadwork contraption seems to be a pavement striper. Never seen anything like it in my life!

Special thanks to OldOnliner for capturing it!
