From the pool report by Time's Alex Altman:
At about 7pm, Gov. Romney got back out of his bus to say hello to a group of perhaps 10 people; it looked like a large family, but pool wasn't permitted to approach. Your pooler wasn't close enough to catch much of the small talk but did hear Romney, smiling, tell a small boy, "If I win, you may want to say you shook my hand."
