How do you run out of cars?
Well, it's was HOT (106 degrees) and standing outside waiting for a car in your category is awful!! There were about a handful of people waiting for a mid-size SUV and at one point most of the line went and took a van.
The one good thing about Alamo here is that there are tons of computers that you can get into your car without going to the counter which was great to get through that quickly.
