A few years back we had a 3 week stretch where we didn't see temps above -10. I wore a pair of gym shorts, wool socks that came up to my knees, uniform pants, under armor, tee shirt, uniform shirt, hoodie, vest, neck gaiter, knit hat, and i wore mechanix gloves. The only thing that was cold were the tips of my fingers and my rear end. we were told that we weren't allowed to run our package cars, but our union steward and BA made phone calls all day to every driver telling them to just let them idle all day. Nothing ever happened.
