yep, they say we 'pack our fears'.
I wished I knew how to read a topo map when I first started out backpacking. I eventually learned (In the Army, and became quite decent at it, I hope!)
It has occurred to me that many adults don't know how to read a topo map, because there aren't that many resources to learn, unless of course you want to teach yourself, then the material is everywhere.
I was lucky that my high school ROTC and later college ROTC, and infantry training (when I was drafted) was heavy on the topo map skills.!
