Query: It's a really big FAQ

The way the books of this series work is that they took a guide for new rangers in Yosemite with the 100 or so most frequently asked questions, and wrote their own answers for each park. It's a great format because it makes for easy reading beforehand, but it's also quick as a reference when you're there because they're arranged in an intelligent order. There's also a huge reference section at the end with lists, copies of permit forms, and so forth. So the thing to do is read the FAQ before you leave but bring the book and refer to it once you're there.I've been to Yosemite four or five times since I've purchased this book, and still find it useful. Partially this is because if you go in different seasons there are different things to see, and sometimes you just want a pizza and that's in there too (Camp Curry has good pizza, if anybody's curious).
