Castel San Angelo

We continued walking. This is still our first morning in Rome and we've had no sleep for about 23 hours. We're running on adrenalin and doing exactly what Todd told us not to do: "Doing everything at once and not stopping to smell the roses." Sorry, Toddy. Anyway, we're now crossing the Tiber River, heading to the Vatican. We knew we had a tour of it the next morning, but we just wanted to see it.
