Crowds like this are normal before Romney comes to speak. At first they are a little suspicious with the mormon thing but after he is done talking they swarm to the campaign people asking where they should send their checks to... happens all the time.
As long as romney doesn’t show up for these things dressed in a 19th century attire with a long beard and the book of mormon under his arm he will be ok.
You sound like Romney staff, newbie. Are you?
