Inside Charlotte's Convention Center, Fayetteville's police officers are roving the area on security detail.

Volunteering for the duties this week, 20 officers are on assignment at the 2012 DNC, five on bike patrol.

"It's a once in a lifetime thing to do," said Watchman Tim Tew.

Inside the Convention Center are where most of the caucuses take place, the state Delegates gather and the media hold their working area. The area is only accessible with Convention Center credentials.

Brian Gainey, a Staff Duty Officer at the front desk in Fayetteville, primarily works shift work during the week.

"It's a different turn of events keeping us busy this week," said Gainey.

Security inside 'the perimeter' is tightly controlled and streets are even shut down for walkers. Navigating from hotel to hotel for meetings could be tricky and parking is sparse already.

Plan to take advantage of Charlotte's light rail system, The Lynx for easier access.
