Oh, I kind of forgot to answer this other part. Call ahead is obviously good, but it seems like a lot of places are pretty casual for after hours if they have empty spaces. They will usually have some little envelopes and a drop box or slot in the door of the building for after hours. You can just put a check or cash in the envelope, mark what spot you used and drop it in the box. So that may be a possibility for a lot of places.What if it's an emergency and it's outside business hours, can I just show up and hook up the car?
