I'm perfectly happy to ankle express and/or transit as needed, taking in the architecture, classicly dressed folk and the...well..."air" that is unique about BCN, truly one of Europe's most beautiful cities. I just want to take it all in and keep enough mental pictures to satiate me until I can go back again...and again. Alan, whatever is easiest for you is great with me...you've already done a ton.
That said, start the countdown clock...83 days. Can't wait.
