Red Square was open to pedestrian traffic and it was a gorgeous sunny day, so I took some more pix. Here is Lenin's tomb with the reflection of yours truly in the bottom lefthand corner. (I'm the one holding the camera.)
I haven't been in St Basil's yet, but my gosh, what a magnificent building.
Legend the Terrible has it that Ivan the Terrible liked it so much that he had the architects blinded so they could never build anything so beautiful again. I guess he figured, "Heck, they're already calling me 'the Terrible,' so why not."
Here's another picture of the square in which you can sense the scale of it.
