Gun was in my pocket. I didn't feel like being the center of attention with so many Japaneese and British tourists there. The idea of a citizen with a gun would have drawn attention away from Old Faithful!
Also, ironically, Cody Buffalo Bill museum (which is the largest collection of guns in America) is a gun-free zone according to their pamphlet. I kept mine in my pocket, unlike the museum guard I talked to, who was bummed out that he wasn't allowed to have his gun on him.
