My first backpacking trip happened in the summer of 2006 in the gorgeous mountains of north California, thanks to my friend Paul. At the time, I was quite ignorant of what I was getting into but just liked the idea and the challenge. From Aug 16th to 28th, Paul and I walked 170 miles on PCT (pacific crest trail) from the horseshoe meadow (abour 25 miles south of Whitney) to reds meadow, most of which is overlapping with JMT (John Muir trail). We walked through Sequoia NP, Kings Canyon NP, John muir wilderness and ended in Ansel Adam's wilderness. The original plan was to walk 202 miles into Yosemite and stop at Tuolumne meadow, but I pulled a muscle next to the left shin so we had to call the last two days off. Nevertheless, we walked a long way and covered the most scenic and hardest part of the trail. It left me with many wonderful photos and sweet memories. I have since done many other backpacking trips, but this one is the first, the longest, the hardest and the most memorable. The journal was written in the two weeks right after we came back to civilization, when I was still more or less in the backpacking mood. When I read it myself these days, I laugh at my own boldness and silliness. \n[[2006 JMT Backpacking 170 miles|trips/2006JMT/backpacking.htm]]\n\n[[Grand Canyon R2R2R|]]\n\n[[Half Dome|]]\n
