Day hikes are the perfect opportunity to play with a GPS and practice using PSK's. Some folks don't like GPS tho' so . . . one reason I'm not fond of PSK's that are packaged like Christmas presents -- Do not open until Christmas morning so you can be surprised. I prefer some of those survival tools/items to be EDC users with maybe a Christmas present for new spares. What's in your pockets? Knife, lighter, LED flashlight. . .
