If your travel schedule will take you to the northeast next week — specifically to New York, Philadelphia and/or Washington D.C. — you might want to rethink your schedule. If you can’t, you should study the itinerary for Pope Francis’ official visit to the U.S. and try to work your schedule around his. Why? Because millions of the faithful are going to be thronging those three cities to get a glimpse of His Holiness, and massive security precautions will be in place — and the result will be overcrowded public transportation, massive street closures, monumental traffic backups and general chaos and disruption for visitors who need to get to a meeting. The folks at TravelSkills have compiled the data you need to avoid the chaos, and you can check it out by clicking here.
