Yesterday morning, we drove over to the airport, just to check out if it would be any good to park for a night. We've parked overnight at many small airports, but Tupelo, Mississippi is a little larger of a city. Sure enough they have a decent sized parking lot and less than half full. And, from where we parked, we got a good free wifi signal from the terminal.
I went inside the very quiet terminal and looked for somebody to ask. But couldn't find anybody. I finally went to one of the two car rental counters and explained to the lady that we wanted to park overnight.
