>I'm just wondering if this really is something you can do for the first time having gotten all your information out of a book?
Short answer: Yes, especially if you have a backpacking partner. I found that my first solo trip (after my wife gave up coming along) was the hardest. Being alone at camp made me feel the isolation even more.
However, there are certain steps you can take to make the experience a good one:
1. Make a list. Check it twice. There's nothing like discovering 20 miles from the nearest 7-11 that you forgot to take a lighter. Mmmm. Dry Mountain House beef stew — crunchy and good.
2. Wear your backpack (the lighter the better, of course) around for short trips, even if it's around the house or the local park. Wear it enough that it feels like it ought to be on your back.
3. Do everything a few times before you go. Setting up your shelter should feel like second nature. If you have to do it in a blinding rain, you'll appreciate it that you practiced.
Lighting and cooking with an alcohol stove looks easy, but it can be a challenge the first couple of times, especially if you've done your cooking for decades in other ways or you're doing it in a monsoon.
Practice. My family was delighted with the MH Beef Stroganoff with Noodles I served them two nights before I hit the AT. :-) Okay, maybe they weren't, but I knew how to fire up that stove, you betcha.
If you're not used to sleeping in a tent, spend a few nights in varying weather conditions sleeping out in your backyard, or whatever. Listen to the (mostly harmless) noises. My first BPing experience many years ago was a sleepless one because of those weird noises. Get used to the sounds and smells and joys of the outside at night. (I learned to love the night this way and am now an avid all-night stargazer.)
In other words, get familiar with what you CAN get familiar with because there are going to be plenty of unique, daunting, challenging, and wondrous experiences to fill your day and night.
Have fun! (It is fun, you know, but you need to know it already.)
