PAT needs to work to place more machine around the county... Like how the banks work to place their ATMs in conveient locations, PAT needs to think along these same lines.
I would work with Giant Eagle to place machines there so that people do need to stand in the CS line to refill their cards.
Also place machines at Duquense University, Point Park College, Robert Morris... Colleges that don't get free passes, but still get PAT discounts. Maybe PAT can have these colleges issue Students ConnectCards or even bake the CC into their IDs like Pitt and CMU, and have a machine or 2 so they can refill their cards right on Campus.
Also PAT rent a space in Oakland to place a couple of ConnectCard machines where the majority of riders can easily get to it....I find it insane Oakland has Nowhere to refill ConnectCards.
