Ground-zero hunting technique
Just a few random thoughts for now:
======1====== Mark the spot and keep track of where it is. If it is truly the center of your search, then don't let your focus continue to drift in one direction unless there are definite clues that take you that way. ======2====== Look for that flattened patch of leaves where everyone stands as they open the box. ======3====== Look for the path from the closest trail to the flattened patch of leaves. ======4====== Look for that tree... rock...stump... that just screams CACHE to you. It probably did to them also. ======5====== Look for an unusual grouping of natural objects. Sticks seldom fall into hollow trees or under rocks. Rocks seldom pile themselves into small cairns. ======6====== Look for no moss or lichen. If a group of rocks are moss or lichen covered except for one, that one has recently been turned over so that you are seeing what used to be the underside. ======7====== Look for the broken branches in the evergreen tree, the bent lamp post skirt, the extra bolt. ======8====== Look up. Things are not always on the ground. ======10====== Look around. Circle the ground zero at an ever increasing distance while looking for all the above clues rather than making straight line plunges away from ground zero and back.
