I use my GPS everyday. I use it to navagate through town on unknown roads and to track my mileage for reimbusment. We have 2 Garmin Rino 120's and use them to play hide n seek with my kids (we live adjacent to Forest Service land). When we are in a large parking lot we mark the position and return to it with ease. We even use it to find each other in the Stadium. If you don't carry it with you it won't get used. I also use it to find and return to dive sites. Of course the reason I bought them was for hiking and mt. biking.
