Oh Seattle, you had me at hello. It was the first city I'd ever set foot in other than Pittsburgh. Second was Vancouver. I was eight, and it was love at first sight.
This reminds me - heard a bit about Chicago mass transit getting corporate sponsorship from Apple and others... Has PAT explored that? Google is in town, maybe they could sponsor the routes that stop by their offices... UPMC could sponsor some routes, other businesses *ahem, (W), ahem* could sponsor routes near them *ahem, (13k), ahem*... I normally am not the biggest fan of involving corporations in a civic manner, but if it's less service or sponsorship, wouldn't it be worth a look?
