I feel very fortunate to have been able to visit the UK twice in my life, but there are so many places I wish I could have gotten to, like the Imperial War Museum. Too old now, and no money either. I did manage to get to the D-Day Beaches of Normandy just prior to arriving in London in 2006, and that is something I will never forget.
And now, what with the damned Muslims terrorists, the insane lefty LUVVIES and their stupid kids, it's no longer "safe" to go there. I doubt that we'll ever go back; sadly.
But at least you and I did manage to get there and see some things/places. :-)
