My first and only scout camp was at Goshen, VA in July 1968. I made 2nd class, earned the swimming merit badge and mile swim patch. After summer camp, I pressed forward to finish my First Class requirements before moving back to San Diego. I joined Troop 857 in Chula Vista and made Eagle in April 1972.
We had a few out of shape kids in both troops. Fortunately, the "shakedown" hikes were structured such that the leaders didn't have to split equipment or physically move them along. By the time we were going up Mt San Jacinto or San Gorgonio, everyone was in pretty good shape. The 30 mile "Camelback" through the Cuyamaca mountains and much flatter "El Camino" hikes were good preparation. The real hiking fans took the 14 day Sierra Trek including a climb to the summit of Mt. Whitney. My lungs weren't up to that level of exertion.
I did two trips to Philmont. 10,000 feet is the highest we hiked there. Did a trip in the Rockies once a few years later with a couple of buddies. After 3 days in the car we hit the trail as soon as we arrived. I had to stop about 2 miles from our destination as my legs cramped up bad. Went to sleep and didn’t wake until the next morning. Felt 100% then.
