Does the population density and traffic patterns of the Portland-Auburn/Lewiston corridor warrant even half of the round trips proposed? It just sounds like too much service for too little potential riders. If (and i emphasize the "IF" to no end) there are that many residents in the area without a car then i can see this project being a success, especially when you consider 1) the direct access to the waterfront/downtown 2) service running til 2:30am (much later than even Boston) and 3) the access to the airport.
