I have a bunch of concepts for light rail and streetcar line concepts for the Phoenix area here:

Which of them is your favorite?
My favorite is the Pink, not because of the color, but I think it would be a great line to connect three major malls (Chandler Fashion Center, SanTan Village, and Superstition Springs Center) plus Downtown Chandler, plus it is the closest to where I live. The Chandler/Gilbert area is in need of better transit service, and a Pink Line along Chandler Blvd/Williams Field Rd/Power Rd would be a great boost for the area.
