We've heard a lot about the headline events at the UN.

But that's not what's catching my attention this week.

I'm at the United Nations this week as a press fellow sponsored by the UN Foundation.

One thing I'll definitely remember most is the less formal break-out sessions on the sidelines of the General Assembly.

I've been photographing these events, including a talk by Nobel Peace Prize winner Mohammed Yunus about innovation and UN after-parties for African leaders.

It's outside the General Assembly where country presidents, top diplomats, and other leaders come together to discuss politics, and have some fun, in an informal setting.
