A little like New York, I never really gave much thought to visiting London. I figured it'd be an easy enough place to visit when I was old. Plans changed, and I ended up having an opportunity to spend a few days in London during the very hot summer of 2006. It felt like you couldn't go anywhere in the city without seeing or experiencing some sort of history. I was hooked.
There was quite a bit to see and time was short. As it turns out, given the exchange rate of the dollar to the pound, it was just as well; I couldn't afford to stay a minute longer than I did. Fortunately, much of the best of London can be seen and experienced for nothing ... nothing but a bit of time.
