It was a wonderful trip, the best I have ever done, and I was nearly self-supported on trout, Top Ramen, rice, tortillas, oatmeal, and Kool Aid with cyclomates.
Cyclomates are the milestone that separates generations. A few of us old timers know what it is.
I ate trout almost every day... and it can take time to catch dinner. I usually broke camp around 8 or 9 in the morning and stopped around 3 in the afternoon to fish and enjoy myself. And when I found nice places I stayed for awhile, such as the Kern Plateau where golden trout was plentiful. This was in the days of no wilderness permits and almost no one hiking up Whitney. The only permit required anywhere was a campfire permit. I left Kernville on Apr 1, 1971... so it was very slow going at first!! I got to enjoy 3 seasons; spring, summer and fall. Lots of snow on the ground the first two months, but overall nice weather.
I knew nothing about the JMT or PCT. My only maps were NFS maps. They were free at the Ranger stations and similar to the ones sold today.
BTW I caught 5 species of trout one day below the Forks of the Kern (rainbow, brown, brook, golden, and kokanee salmon).
I did not know that backpacking stoves existed, and I still have (somewhere in the garage) my Boy Scout style "mess kit" and a small pot that I used over camp fires. My pack was a Kelty D4, and I had a Canadian brand down bag. I used a tarp as my shelter. Pants were military wool trousers and I had a Pendleton Wool shirt. Big heavy leather boots with Vibram soles. Can't remember what kind of jacket. Snowshoes were ancient looking things. Rain gear was a poncho, which sometimes doubled as a ground sheet. Still have the Buck knife I took on that trip. I had a conventional spinning reel set-up for fishing. It never dawned on me to weigh my gear, but must have been well over 60lbs at the start and at re-supplies.
My prior backpacking experience were trips in high school with a friend and many solo trips... all in fair weather. I did have extensive military survival training after high school, and before this trip. I walked into Lone Pine (twice) hiking each way for major re-supplies. I did a few other minor re-supplies, but can't remember exactly where. One might have been Mammoth. At the time, I was not very familiar with that part of the Sierras.
I had no goal other than to wander around for about 6 months and that goal was achieved with great success. I knew little about the Sierras other than time in the southern Sierras around Kernville and the Domeland Wilderness. I had some maps and went places that looked interesting... although I had a general idea of where I was going before I started the trip. Basically I hiked some of the most spectacular country in the US, and did not know before hand that it existed. Sort of like when I bought Sgt Peppers Lonely Hearts Club Band on the first day it was released... never heard a single song on the album, and ended up listening to it over and over for two days... even ditched school to do it.
I had never read anything about backpacking until I finished this trip and picked up the first Complete Walker. Been refining my gear ever since.
