Activities begin with an invitation-only ribbon-cutting ceremony at 9 a.m., when bands from Niceville and Crestview high schools will perform.

Gates will open for the general public at 10 a.m.

The troops will offer tours, demonstrations and displays. Officials suggested bringing sunscreen and strollers for the all-day outdoor event.

Dining facilities will be open. Brownlee said the menu would include everything from barbecue to seafood for $4.25.
