I go on multi-day backpacking trips in isolated areas of Utah and have done so for most of my life. The High Uintas Wilderness area in northeast UT is a favorite as are Coyote Gulch and other isolated areas in the remote southern UT deserts. Ialso do mountain climbing in the Wasatch nearby. I've never had any true emergencies, knock on wood. But I've had enough close calls to know that having a Spot is a very smart decision. Things can go from fine to disaster in the blink of an eye.
Plus, it does make things easier on my wife when I'm gone for days with otherwise no link to the outside world. Yeah, she worries. Already have a trip planned for the Wind River range in Wyoming for this summer. Can't wait! I live for that stuff. It is by far my favorite 'hobby'.
