It takes a lot of manpower to put on a festival, especially as one as big as South by Southwest.
"One thing that I don't think a lot of people realize is that there's like 200 people that have full time jobs at South by Southwest," says SXSW cofounder and managing director Roland Swenson. "During the event there are hundreds of more temporary workers that we hire."
When it comes to volunteers, Swenson knows there's a lot – even if he's not quite sure of the number.
"You know I think there's going to be over 3,000," he says. "I don't have a precise count, but that's for 15 days of South by Southwest."
