Vice presidential nominee Paul Ryan visited the convention stage to get used to the teleprompters, the lights and the sound while his three children played around at the podium.
The 42-year-old congressman from Wisconsin gives the biggest speech of his career on Wednesday night.
He asked aides where delegates from Wisconsin and Michigan would be sitting, as well as the location of running mate Mitt Romney's box.
"I'm going to point to them in my speech," Ryan said.
That's about all he gave away, even when reporters pestered him for a preview of his remarks.
"You'll find out tonight," he said. "Why would I spoil it now?"
