I've enjoyed reading everyone's thoughts. I've backpacked in the Sierra and other mountain, coastal, and desert regions for over 40 years. I began backpacking with the Sierra Club in small, local chapter groups, often with people I didn't know but with leaders that I came to know well. I did my first solo hike about 20 years ago in coastal California. I've only gone solo about seven or eight times, the last a month ago. I realized that if I want to backpack (and I do, I always do, I love it as much as I did on my first trip to Sunrise Lakes in Yosemite with my brother when I was 17), I'd like to be comfortable going alone. Because I've so often traveled with others, it was different at first. I love to get up early too, and it's wonderful to enjoy the beauty and silence of the morning. What helped me was reminding myself of how experienced I was and that there were few things in the wilderness I hadn't faced. Backpacking is generally a slow, deliberate thing, and there's plenty of time to consider what you should do or want to do when you're out there. Dangerous situations can be avoided (with the exception of lightning, but I agree with the post above that there's nothing for that but luck and if possible, a small grove of trees)
I also enjoy books when solo.
