|Like to add the following on this list:
1. Take time to master using your equipment before heading out. You're basically on your own out there (unless your backcountry camping with a buddy), so you need to not only know how to use your equipment but also how to fix it if it starts conking up.
2. Stack up on antacid. Even if you got those water filtering stuff, you can't really say how well it will sit in your stomach, and having a bad stomach is one of the worst things to have while you're out there.
3. Take your time. You're out there to enjoy the outdoors, so take your time and just soak everything as much as you can.
