Excellent post, EF. Back in the early 2000s, I was an investor in a hunting business up in Maine called Bowlin Camps. A bunch of us retired and active duty (I was still active then) USN/USMC guys owned it. Maine state government told us in order to "guide" we all had to take their State run course for "Maine Guides". Lots of survival stuff ( old stuff to a lot of us that had gone through the various survival schools), but they really delved into the land navigation/map reading curriculum and no GPS stuff. Anyway, nowadays I think we've all been spoiled with GPS, cell phones, etc. , but it's good to remember:

True

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
