I don't think anything, I have visted several times bearing in mind I live near it... and even sailed under it ... have you ever sailed on the sea, anywhere ...?
Who wouldn't prefer to see something real and exciting, and why wouldn't anyone wish for a trip to London?
(EDITTED: Oops! I was responding to an earlier question, regarding whether I would rather go to Arizona to see a rebuilt bridge, or prefer to see the tower bridge in London; I hadn't realized there were already several posts, after that one. SORRY! I will try to be more careful, I promise, but I admit I have made this same error numerous times, and have been careful, but still make the same mistake at times.)
Do you ever make the same mistake repeatedly, even though you are truly trying not to?
