I came to Boulder on a sad mission: find out how amongst such a majestic backdrop my 21 year old nephew Gabriel a student of University of Colorado and an avid life lover could do the unthinkable and take his own life?! At his memorial in his honor my family wants his adventures to live on and I was having a hard time with the concept thinking maybe it was glamorizing suicide, but guys maybe you too could do the hashtag in Gabriel’s honor #adventureon
