AFROTC will sometimes have "unofficial" programs that are done in the summer. Our detachment is relatively close to local AFB and we are allowed to participate in the Ops Air Force program with the Academy cadets. The difference is that you have to pay for transportation and lodging if you live far away.
Most of my ROTC group just drove 30 min to base. But once on, you have full access to the shadowing program (incentive flights, simulated training, mentorship boards....etc). If you don't have this program at your det and you are by a base then be the cadet that sets that up. With the facetime and task that would be accomplished, I would argue you would easily be able to pull a high CC ranking assuming everything else is in order.
