Here's an excerpt from an email I got from a friend earlier this week on Monday:
"The weather in Roma feels like --believe it or not -- cooler
than London. We stood in line at St. Peter's today (a late
start...don't do that!) only to be turned away for not wearing more respectful clothing. We were in longish shorts and
that did not cut it with the guards/security at the entrance. How could I have forgotten? Anyway, we will give it another go tomorrow, and earlier."
