My kid’s there, as are 48 other college kids from our church. You can actually listen to the main sessions online, they keep them up at their site for 24 hours.
Go to this link and hit “playback.”
First main session was Louie Giglio, second main session was Francis Chan (I think Piper speaks tonight.) Worship bands are Matt Redman, Chris Tomlin, Charlie Hall, David Crowder, Hillsong United...and a few others.
