The goal of the Hour of Code is not to teach anybody to become an expert computer scientist in one hour. One hour is only enough to learn that computer science is fun and creative, that it is accessible at all ages, for all students, regardless of background.
Transit services. Union Station serves as a transportation hub for Portland. Portland's Greyhound bus station is the next building to the south, having moved to a new building there (from a location in the center of downtown) in 1985.
Last stop is the Greyhound Shuttle Depot on Duval Street in the center of Key West. The trip is an hour and forty minutes from the airport to Key Largo; Key West is about two and a half hours farther. The shuttle service also provides transportation between islands. Tickets may be purchased at any Greyhound bus station.
