They do exist...

Backing around a corner into a building. Sounds easy doesn't it?

Bright sunlight outside, dark building inside. Piece of cake.

 

Sounds like an intersting challenge to me Brickman! I wanna try it! Could you bring the truck out here so I can try it! We'll go play on Main Street! There are alot of those kind of challenges up there!

 

I did just that in IN at a shingle plant. After I got in the dock crew tells me about all the other guys that can't do it. The walls around there were evident that a lot of guys left with their trailers in worse shape than when they arrived.

The reward for getting in was being able to tarp in the shade on that hot day.
