My apartment complex has one designated parking place per apartment. Mr. Sirius and I have two cars, and since I work at home and it's often icy here on winter mornings, I let Mr. Sirius park his car in the covered parking space. This isn't a real problem for us. However, one of the apartments in the building next to ours houses at least three single guys, and each of them has two vehicles. There's one designated parking place per apartment, which results in most of the guest spaces near our apartment taken up by vehicles belonging to these three single guys. (One of their cars has a car alarm that keeps going off right outside our bedroom window, too, but I digress.) If I get home late from a function, I'm often hard pressed to find a parking place on our apartment's side of the complex. I live in the 200 building, and I've had to park by the 2100 building and hike through the dark to get to our apartment.
And when I worked at the Air Force hospital, there were numerous briefings about Tricare for retirees. Those of us who routinely parked in the employee spaces on the north side of the building had to find other places to park, because those spaces had to be left for the retirees. Mr. Sirius and I carpooled, but we'd still have to park clear on the opposite side of the hospital, usually in the mud. I feel for the person who gets stuck with the parking mess on football weekends; my feeling was, there was plenty of parking on the north side of the building since we had four designated employee lots on that side, but we couldn't convince the hospital hierarchy of that.
