Was just there at re:invent the other week, and I couldn't point to anything different about the airport WRT security and TSA. Very long lines, traffic in and out of the airport was _insane_. My last impressions of Vegas were the terrible traffic, long lines for a limited selection of airport food, but hey, if I wanted to play slots, there they were.
Yes, F1 had wrapped up the week ago, but it didn't seem like they were hurrying to take anything down.
