Parking was astonishing, to say the least, but we are here, happily. The crowd is massive, but this convention center seems much larger than those in Houston and St. Louis. I expected the street to be thronging with protesters, but I have only seen one with an anti-Trump shirt. I'm going to head out onto the floor and will post more updates in a bit.
For the record, this crowd is consistent with my past observation that the crowds at NRA Annual Meetings are the most polite, orderly, and calm groups of people you will see in any large venue. A large crowd is not a pleasant thing, generally, but this group is not so unpleasant as most crowds a fraction this side.
