The only pics I've seen are people lined up to get in. I figure a picture of people not getting in would look similar. But directly to your question, no, I have not seen a picture of thousands outside the full venue.
I didn't even know Crooked had a rally today. Ahh, I see it. She and Pocahontas in Manchester, NH. Some photos here. I'd guess on the order of 1,500-2,000.
Drudge has a nasty picture of Hitlery up - does anyone know if that’s for real?
