Not ages ago...just decades ago...used non-gps tools doing night nav & evasion training. Fun, fun, fun!
Oh yeah...not as professional, I was a Brownie & a Girl Scout growing up in ND...my aunt made sure I knew compass skills, how to build fires in the snow, how to build cold/warm weather shelters & so much more. She has passed but the education she provided to me has not gone unused...I've used them all. RIP Auntie
