The big takeaway is that if you have never been to a Trump Rally in person, then GO! Much different experience than you see on television. In person you get a better sense of Trump's body language. It was surprising to see in person how RELAXED he is. When he came on stage he was just very calmly strolling, almost meandering, calmly tossing MAGA hats to the crowd. Also he you can see how relaxed he is while speaking.
The other big difference from watching on TV is you can actually FEEL the crowd. The reverberations from the loud cheers. Also very thrilling was when Marine One Helicopter landed above and not only could you hear it, you could FEEL it.
