I think I've seen all of his stealth camp episodes, and they've only been outside airports. (Once outdoors, once in a parking lot.)

I think a lot of the humor would be lost because he couldn't get his camp stove in to cook. Or maybe he could, but would risk arrest if caught with it...

I didn't think I'd see Steve mentioned on this site! The camp stove would probably be fine, but the fuel would be an issue. I wonder if axes are allowed in carry on?

electric hot plate?
