Overheard an American tourist visiting Windsor Castle "I wonder why they put this so close to Heathrow airport" -)
Much as Europe changes, thankfully old landmarks do not disappear.
As we plan next summer's trip, I recalled my two years in Europe were greatly enriched by a book of walks in major European cities. Written by George Oakes, a NY Times travel writer, in 1965 it described every little square, fountain, church. It has since been updated periodically by Alexandra Chapman.
Saint George, as my wife calls him (she is not as big a walking fan as I am), made me explore European gems like the canals of Bruges and the aqueduct of Segovia - and discover little secrets in Paris and Rome the tour bus guides do not even know about. I finally gave up my dog eared copy a few years ago and got a new one.
Get your self a copy - or if you want walks for a selected city, my daughter will be happy to make you a copy. For a small fee - in euros, please for her fund when she Eurails the continent in 4 years. By then she probably be able to avail of a GPS enabled Segway - and Saint George's classic in e-book format on her iPod with dog ears painted on....
