I have lived abroad for more than 12 years and am accustomed to using diverse types of public transportation - but they are not free. The Orbit system is fantastic! I love not having to rely on a car to run errands or get around Tempe in general. It's wonderful that some progressive areas in the US are choosing to lower pollution and help the environment with good, free public transportation. Than you Tempe for the Orbit system (and also good bike lanes :))
