MOMBASA, Kenya Matt Reinhardt didn’t know what to do when his company asked him to take two weeks of unpaid vacation to cut costs. His first thought was to head to the beach. The Midlothian resident thought maybe he would travel to Mexico with his wife, Dina, twins Libby and Reed, 3, and son Owen, 4. But this was an unexpected vacation, and Reinhardt wanted to do something meaningful.
