The announced start time is either 3:30 or 4, depending on which Obama announcement you believe. That's when they open things up. "Get there early," they say. Expect Clinton to begin ... well, who knows? I'm guessing 5?
The entrance to Pullen Park is on Ashe Avenue. I wouldn't try to drive on Ashe, however. It's a very small street. There's lots of parking in the N.C. State lots, many of which are within a 1/2-mile of Pullen Park and open to the public on a Sunday. Or park somewhere on the Dorothea Dix Hospital campus, which isn't that far away on the other side of Western Boulevard.
You need a ticket to get in. They're free. They're available online only. Go to http://ofa.bo/ClintonRaleigh — or the slow way is through www.mybarackobama.com.
