What I want to know is, where the heck is Clark Kent supposed to change into his Superman outfit these days?

Regarding office Bug-in/Bug-out kits, I work for a large international oil co. We have a closet on each floor (sealed with a zip tie) that allegedly has emergency supplies inside. In my case, however, I only live about 3 miles (5 km) from work. If Wurst came to sausage I could hike home, no problem. I do make it a point to always wear season appropriate shoes and coat to work, even if I'm not planning on going out of the office that day.
