Isn't there just a bus for folks to get back and forth to the airport? I would have thought that there would be lots of people living in PM and working at the airport. Isn't there just a city bus or collectivo from the airport rather than the ADO? Isn't ADO like a big Greyhound bus or something? How do people get back and forth? Doesn't it just run up and down the highway stopping at the PM intersection?
