Have you thought about working with an asphalt crew, in the middle of summer, in the south?
Traffic wisking by at a calm 60 miles per hour a foot or 2 from you.

I live in the Dallas Tx area, so you know it gets hot here. I watch these road crews , and I just gotta say, THEY MUST BE NUTS!! That hot steaming asphalt, or maybe out there all day, with no shade anywhere, pouring concrete, they can have that job!
