He enjoys hiking along with other activities like skiing, snowshoeing, surfing, and any other sport his friends recommend to him. A unique skill Owen has that very few people know about is his ability to walk and flip on a slackline. One day, Owen hopes to visit the Great Barrier Reef, see a glacier in Iceland, and skydive from a plane.
