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.
Getting Here By Ground. Greyhound offers connecting service to Palm Springs. The Palm Springs greyhound station is located just outside the city center, so transfer arrangements are required. From Los Angeles it currently runs 4 times daily and from San Diego 2 times daily. Purchase Greyhound tickets.
