Step 1: Preperations
Sorry about not having pictures, I'll add some within a few weeks.
Now you have maybe chosen to get on your way.
Make sure you find out where you want to go.
You'll want to pack a few essentials, make sure you pack light enough to walk upwards of 50 miles a day.
Things to pack:
1 Long sleeve button up shirt.
2 pairs of pants
4 sets of underpants
1 pair of shorts
1 road map (Rand McNally is very useful)
1 Survival knife (Make sure it is legal in the ares you will be traveling through)
1 Swiss army knife (Standard 10 tools I think)
1 set of good heavy duty sneakers (Preferably steel toe)
1 gallon water jug
2 10oz. water bottles
1 sleeping bag (-10c rated minimum)
Warm coat or jacket
Good big Backpack (preferably one in a dark colour)
At least and I mean at least $100 (My first time out I started with $0 and it screwed me up)
Other various things:
Cell Phone (Tracfones are best because of the non-monthly payments)
Loose Drum Tobacco and papers (if you smoke, they last longer than regular cigarettes and is cheaper ;P)
Notebook and pens (to write your best selling novel based on your trek)
Enough food to last 5 days (Ramen is best(It can be eaten and used as a fire starter))
