We came upon these fire men in the middle of the afternoon climbing up and down stairs in an effort to keep in shape. There was no fire! There were three on the stairs and three more exercising in front of the firehouse, one doing push-ups, one with a huge exercise ball, and one jumping rope. The most interesting fact is that this firehouse was tucked in between what passes for skyscrapers in Las Vegas. City Center. We were on the elevated walkway behind Aria.
