The NFL in their annual Pro Bowl conducts at least one practice at one of the military installations on Oahu, and I snuck out of work to attend with the family. The two teams practiced separately and consecutively at the same field on Hickam AFB. Practice lasted about an hour with autograph sessions following. It was pretty awesome as the crowds were smaller due to it being military only, and the barricades were right off the sidelines, which afforded my wife and I some pretty good photo ops of our boys in black and gold (Or in this case orange, white and gray).
If anyone wanted any pics of other players at the Probowl, I likely have them. My wife was doing her best papparazi impersonation and got a host of other shots while we were there. Otherwise, take care and aloha.
