Are you a busy person? Do you not have time to visit European cities? Then you should watch this 2-minute video of seeing Barcelona Spain. It pretty much shows you everything there is to see and do in Barcelona, but I recommend visiting the Catalonian city anyway. It's pretty cool.
See Barcelona Spain in no time.
I'm currently trying to write another CrosbyReport™ for a trip I took to Barcelona, Spain a few years back — but don't hold your breath for it.
