Not always gold.
Received a call today, set of important keys lost over 2 weeks ago, snow plows have come through and piled the snow at the end of the lot.
Once I saw the snow mound (over 4′ high) my immediate reaction was to let it melt for a few more days and come back.
After second thought as long as I was there I told him I would at least skim over the top to see if it is shallow enough to detect.
After a few minutes I hit well over a foot down but so luckily as it could have been in the middle and totally undetectable.
