My dad gave me The Hobbit when I was about 10 and sick in bed and I still remember reading it for the first time and having weird and intense dreams. It took me a few years to get through the Rings trilogy (or nonology, or whatever it is), and in high school I got in trouble in English class for laughing because I was reading Bored of the Rings (the teacher confiscated the book and gave it back two days later saying, jeez, that's hilarious). I didn't really reread it until the late 90s, when I heard they were making a movie (that I thought would be lousy). I've got several friends who read it every year or so, and one guy I knew years ago read it on a long cross-country motorcycle trip. That seems like the ideal way to make your way through it. Just imagine there are Black Riders on your tail, and watch those miles whiz by.
