The walk is fairly long. Always a nice walk on a cool, August day in Phoenix

They are going to extend it to Terminal 2, it's just going to take a few more years (2020 I think).
Furthermore, just because a transit system doesn't fit one person's needs hardly makes it "useless". It's a much better feature to get to the light rail station than the buses they used to run.
