Lots of activity on the JNCR site related to this.
In addition to military police and the normal activity related to the Air Base on this system, found 2 talkgroups I never heard before.
25278 and 25279. Both definitely have to do with the public and the air show.
Sounds like they are directing the shuttle buses.
Still trying to determine exactly what they are, but are interfacing with those checking bags of those entering (not them though, as they have just learned those folks were released 2 hours ago - or around 3pm).
The talkgroups are coming through the Naval Academy site.
