I looked up where Trump gave his rally speech last night in Nevada...
Big League Dreams. https://lasvegas.bigleaguedreams.com/ It's a baseball/softball field complex with batting cages about 5 miles north/northeast of the Strip. Their claim to fame is having replica standiums that mimic Fenway, Wrigley and Yankee Stadium among others.
Besides the on-site restaurant (burgers, hot dogs, nachos, etc., ) the closest local eats are McDonald's (of course), Golden Corral, Jack-in-the-Box and Fat Boy Hamburgers (I'm not making that up). Their "20,000 square foot pavilion accomodates cheereading and dance competitions, as well as corporate events and parties." That includes weddings (I shit you not)... https://www.wedding-spot.com/venue/10455/Big-League-Dreams-Las-Vegas/
Overall, the reviews people have left are fairly positive but they only have a 3/5 score.
Like in Iowa, the facility looks like a VFA hall or barn and the crowd size is not remarkable in any way. My guess is that the owners are Trumpers and he got a huge discount. I can't imagine Trump's campaign shelling out money for space at a Wynn property or some other casino. I'd guess there were less than 750 people there. From this picture it looks like less than 400 in the shot. And overwhelmingly people between 40-70. Notice anything else about the makeup of the crowd?
