One fun thing about exploring a new city is getting lost. We were on a quest today for an obscure little shopping street that we had read about on the web. We had already seen the creme de la creme shopping boutiques and were hoping for something a little different.
We never quite found it, but on the way to what turned out to be nowhere, we stumbled upon this view. And when you get "lost" and accidentally stumble upon the Eiffel Tower, life is pretty good. We also found a random ancient Egyptian statue on a main street we just happened to be walking on.
The point of it all being that while certainly it is good to go somewhere specific, there can be some pretty cool discoveries when you end up in a random place.
