As I am past 35 I can identify and use the tools shown, minus the slide rule. Never learned.

I can land nav with the best of them. When I went into the Army I could read a map, make a map, knew my pace count and could use a compass. Now they start map classes with the memnoic "Never Eat Soggy Weenies" - north east south west - to get the rudiments of a map into the heads of the trainees. Scarey huh?

I knew all that camping and hiking with the Scouts would help me sometime.
