That's cool. In 1985 two of us rode to Canada and back with the above instruments. We still marvel at how disconnected we were for that trip; 22 years old and free as the wind. Below is a picture taken in Canada on that trip. That's Lake Ontario behind me. I didn't even have a windshield... no heated gear... not a stitch of Goretex anywhere.Yup! I always take a compass when hiking, and prefer a good old fashioned topo map.
I still have several slide rules, including one round aviation specific model. I used that in the regional jet for years to keep proficient in case the GPS or FMS crapped out. There were some days we'd be back to "green needles" terrestrial nav and manual fuel calculations. Back in the day the military jammed GPS regularly. The era of dual GPS feeding dual FMS upped reliability substantially!
They went to the moon using a sextant and slide rule. I can get to my next camp site without GPS leading me by the nose.
We both turn 60 in June and plan a motorcycle trip up Pacific Coast Highway in CA. I'll have my GPS and a Spot Satellite tracker to manage the wife's anxiety.
