For added context to facilities access at USAFA, here are a few bullet points to paint the picture:
1) USAFA is a campus with more than 18,000+ acres of land. That is a HUGE space to protect.
2) It is a military base that has very few areas open to the public. There are two points of entry into the campus - North Gate and South Gate.
3) As a college with sporting events open to the public, sporting venues in the vicinity of the cadet area are generally open to the public but on occasion, the school reserves the right to further restrict access completely to military and/or essential civilian personnel. This could be in cases of heightened security or bad weather.
4) Under most conditions, visitor access is only allowed through the North Gate. Access via the South Gate is generally restricted to authorised contractors, employees, residents who live on base, students who attend Air Academy High School, cadets, or military. On game day when the stadium is in use, the South Gate is opened, but there are interior checkpoints that get manned to prevent unauthorized access to interior parts of the base like housing and the cadet area.
5) Arnold Hall is the equivalent of a Student Union building. This is one of the buildings that is generally open to the public and a great meeting space.
6) When the Cadet Chapel is open (currently under renovation), it too is open to the public and it is common for visitors to attend church services here.
7) Clune Arena and the Cadet gym are also generally open to the public and can be a meeting location.
8) The Barry Goldwater Visitor Center is open to the public and has exhibits and a gift shop.
9) The nickname of the school is "The Zoo" - because it is common for visitors to patrol the Chapel area and overlook the Cadet area at very close range as if they were looking into a zoo exhibit.
10) Outside of these buildings, there is enhanced security that require key card badge access. This is new within the last 20 years.
11) Students do not have the same freedom as normal college students to hop in a car and leave campus to grab coffee or dinner out. We operate on a class based merit system that provides different freedoms and rewards to different grade levels. Freshman have the most restricted movement and Seniors have the most freedom of movement.
Back in the day..... vehicles could drive anywhere on base, including the Cadet area. This was pre-9/11 and pre-Oklahoma City bombing. As a student in the dorms, we would talk about how easy it would be for a determined adversary to simply put a bomb into a u-haul truck and drive it under one of the cadet dorms and wipe out a significant portion of the leadership pipeline of the USAF.
While the current measures are normal for cadets (it is all they know), to old timers it feels really restrictive - but I certainly understand why.
