Over 200 Catholic high school students are taking part in annual mission trips. Students from St. Dominic will be heading to Tanzania today to spend two weeks immersed in the country’s culture. The Simcoe-Muskoka Catholic District School Board says students will be participating in construction projects and learning about the country’s geography, history and socioeconomics. The students are getting three credits for this trip.  St. Dominic is one of five schools participating across the board.
