Normally I'd pen a long winded speech about climate change and environmental stewardship, but in this case I'll simply say that Valley Metro Rail is a start, and a long overdue piece to Phoenix Metro area's transportation puzzle.
I am frustrated that it's not further expanded, and that it runs along traffic, and stops at the lights, and that the traffic systems don't seem sync'ed with the train schedule.
That being said, I work 8 miles from my house, I don't take freeways, and I would never be able to use this mode of transport for my commute. I will primarily use it for attending sporting events or to get downtown without the hassle of parking.
Bottom line: I like it, and I'm excited for it to grow.
(p.s. I think we missed the opportunity to call this thing PhART - Phoenix Area Rapid Transit, more catchy imho)
