Welcome Newguy!

I'd second what everyone else has said, and just add this: Don't take too big a bite the first few times. Don't take off on some 50 miles in three days thing, pick a nice short (as in no more than three or four miles) hike. Being all alone in the boonies can have a different effect on different people, some love it, others start hearing boogymen with every sound. If you discover that you fall into the second catagory, it is easier for you to bail...
