I was hoping it is there, and can't imagine it is not a feature, but still can't find it. As for the melted GPS unit. Search zipcode 97756, and pull up the "Sticks and Stones Redmond urban cache series #1" geocache for a picture under our Christmas day post. It all started with a wall tent and a fire place. Someone moved my pack a little to close to the stove, and presto! droppy GPS unit. I also lost a camera (a cheap 35mm point and shoot) to the fire.
