He's down there doing his scuba training and certifications on a winter study trip. I know he masked on the plane and he said he did when they all went to the grocery store, but figure once he got down there doing different things, camping, and diving with 10-20 other people, they definitely can't mask all the time. At least he took most of his own equipment and didn't have to rent or use the stuff the prof took down. At least he's not bunking with other people at night. He opted for the couch in the living room rather than 3 to a bedroom.
