"We had a daughter in Boston. We used to visit her on the weekends," says Bob Hummel, the man behind the Website called MassTimes.org. "It was a monthly trip, and it went on for four or five years. We were always in the struggle of finding [Catholic] masses, and that's how it all kind of got started." It's a database of every Catholic church in the United States, listing the times of every mass at each church, a map to the church, and a link to the church Website if there is one. Hummel's own site is as simple as a paper bag, yet his mission is increasingly challenging. After six years of operation, the database has grown to include 22,000 churches. Working out of his Key Largo home, Hummel and four volunteers make about 2000 changes to the database every month. "We get about 200,000 inquiries a year, so there is a need," he notes. "And an awful lot of nice kind words are showered down on us for doing it. So it has been worth it."
