You can backpack. The question is how far, and how high. Take a couple of easy trips that will allow you to break in your equipment and get a sense of what works, what's needed, and what systems make sense for you.

By the time you've done that, you'll have started selecting some new itineraries.

And when you get back from a trip, you'll never remember why you didn't want to get off your butt!
