Very cool, if true

That sounds great. Back when I moved to Columbus, Ohio, in 1996, the buses were $1.10 + 10¢ per connection (bus taken within n minutes of previous) which was just fine and simple. It does sound like the grass is greener in Edinburgh in that regard!

(Admittedly, I've avoided the trams so far as they always look rather full of people! With luck, supply will meet demand … Have yet to try the P&R.)
