It was Dr. Blake’s first visit to the Eternal Città. So I wanted to make sure I brought him to all the must-see spots. Keeping in mind his dislike of heights and crowds. (It was a holiday weekend and the city was packed with tourists.) First stop: My favorite building in the whole wide world: the Pantheon. When I lived in Rome back in the 1980s, I’d stop here regularly, just stroll in and marvel at the dome, the niches, the floor. Now...there are restrictions on how to enter, how many people are allowed inside, cordons holding back the crowds, guards yelling for people to keep quiet.
