The TSA was surprisingly nice here. I always set off the metal detector either due to the multitude of pins in my hair or the massive amount of metal in my bra. Regardless of both those conditions they lightly wanded me, smiled and let me through. When I asked why they were so nice, two guards responded " This is Vegas, we are happy."
As I initially came in the airport I saw a decent sized ad of a blonde woman with bangs, smiling and standing next to a gun the same height as her. I knew I was no longer on the East Coast, but it was a nice, clean and easily navigable airport regardless.
