What if they gave a papal Mass and nobody came? SEPTA yesterday said they had sold only about 50,000 passes for Saturday, and maybe 60,000 for Sunday. Yes, those are double and triple the usual weekend regional rail ridership. But it's nowhere near what SEPTA expected. The transit agency put 175,000 passes on sale for each day. Officials indicated as many as 10,000 people could descend on beautiful downtown Primos to get on those early-morning trains on Saturday and Sunday, Sept. 26 and 27. But SEPTA now has more than 200,000 passes on their hands, and they're hoping sales pick up. That's probably why this week the tone of the officials in the city and the World Meeting of Families has changed. There is less talk of commuting snags, a traffic box, logistics and long walks to venues. In its place there is the 'Francis Festival Grounds.' And a huge push to get people excited about the papal visit. It was expected that 1.5 million people or more would descend on the Benjamin Franklin Parkway on Sunday for Pope Francis' outdoor Mass. So I ask you, are you taking the 'over' or 'under' on that number. Based on sales of those regional rail passes, I'm leaning toward the under.
