The Papal Conclave begins Wednesday in Rome, but on Tuesday, some North Texas school kids got a hands-on lesson on what will be happening at the Vatican. Mary Immaculate Catholic School in Farmers Branch held a mock conclave Tuesday morning, where they elected their very own pope. It's been 12 years since the last Papal Conclave, so for most of the students at Mary Immaculate, what's happening in Rome is a first for them.
