You're half-right: Charlotte has a light-rail system which (so far) only has one line, but is expanding to add a second.

Yes, but does it explain James Horner? ;)

He needs to retire. Seriously. I love me some John Williams, but there was entire 15 minute section of SW:EIII that was just lifted, note-for-note, from one of the original trilogy movies. Keep the iconic themes, but hire someone with imagination (I nominate Michael Giacchino!) to score the rest.
