That's very true Radiorails. I rarely travel by bus but do remember how much more I used to see of a building from on top of a double decker. Much more interesting. The ground floor frontages of buildings, especially shops, can diguise so many good features and we often miss so much of interest. I'm often surprised when I look up above a shop front to find a lovely old building or feature up above. So nowadays I try to routinely 'look up'. It's surprising what you can discover about a place.
