What others have said, plus...

You have nothing about raccoons, rattlesnakes, or insects -- nothing about the dangers of high peaks in a storm -- nothing about being prepared for the season, nothing about the dangers of going out without being able to navigate.

More people endanger themselves by going out with no extra layers of clothing, no way of navigating, no (or insufficient) food/water, and no clue about staying off peaks like Half Dome when it clouds up and looks like rain. There have been no bear related deaths in Yosemite, where the habituated bears are the worst - the bears are the least of your problems.

And you make no mention of the permitting system for Half Dome - nor are there links to any of the official Yosemite pages that would give the reader those details, or the info on food storage, which is absolutely critical for any hiker to have before going to the park. Not just backpackers, either.

And I completely disagree that Yosemite Falls is the best hike in all of California.
