FIRST has recently just released a notice to all people attending the Chesapeake Regional.

Basically
* All things are subject to inspection, including your car
*Parking will be at a remote location
*Entering and Exiting is a pain
* ID's are necessary at all times
Trust me I know what security inspections can be a major pain. A couple of times, I was hold for as much as 45 minutes, for stupid reasons like guards misplacing information. But at the same time, our nation is in conflict and there maybe some individuals who would like to hurt it.
This shouldn’t deter people from having fun like they always have. But I must warn you. Don't misbehave or do something stupid like jump a security post. You can get in big trouble, your team, and FIRST. And they will likely won't host it again next year. Just follow procedures, and I think you will be all right.
I wish I could attend this regional, because my team’s sponsor directly helps build things for the Navy.
