My stash of hand-drawn route cards from before everything went digital

I was cleaning out my backpack and found a bunch of my hand-drawn route cards from trips in the Sierra Nevada years ago. Each one was on a folded piece of grid paper, with distances between campsites and little symbols for creek crossings. I used to make these the week before a trip, copying from guidebooks and my own guesses. Today, I download a GPX file to my watch and follow the dotted line without much thought. It's so much more precise, but I kinda miss the puzzle of it all. Those old cards have smudges from dirt and maybe a bit of trail mix, and they feel more personal. Isn't it funny how the work we put into planning used to be part of the fun? I still use apps, but I keep one of those cards in my pocket as a backup, just for old times' sake.
