Stupidity
If you go to see the Mona Lisa in the Louvre, you probably fight a large crowd and never get close to the painting. Bring you binocs. The smart play is to go to the Prado and see the copy. Then you can actually see the painting.
Same thing with the Rosetta Stone. The real one in the British Museum is kept far from you. But, you can walk 25m across the courtyard and see the copy.
Oh, and I did go to see Yo-Yo Ma a couple of weeks ago. I'm pretty sure I didn't notice if he changed instruments, but he did change my mood for the better. Dang I missed live music. Can you send Joshua Bell to demo the special violin, too? I really must evaluate that Stradivarius, too. Please.
