I had a similar story happen to me. I was coming in the "gate" one night, it was actually just the checkpoint up to the cadet area. The guard was like "could you please pull over to the side?" it was like 1:30 am, and I was thinking "yea yea yea, whatever, I'm not drunk dude" but pulled over anyway. he just wanted to check out my car. I was down there for probably 45 minutes just talking about cars, listening to mine idle.

It's good to have those guys as your friends. afterall, they also write traffic tickets on base!
