Friends.
As you approach your start date please go to http://www.trailjournals.com/index.cfm and setup a journal so we your -friend, can follow you on the trip-of-a-lifetime.
I met "Conductor" while I was on a weekend trip, 2006, (i still work for a living, but will be a member of the class of 2013, at retirement, 66-yo) and followed his entire thru-hike by going to this site.
Conductor, religiously, wrote a one-page journal every nite in camp. When he went into town he mailed his journals to his wife, who posted them on the above site, with pictures. You can have anyone do this for you.
Viewing his journals & pictures on the above site was as if I was there myself.
