I did this hike with the Trail Dames of Maryland.  Trail Dames is a great group for beginner and more experienced hikers.  If you have been thinking about hiking (and you are a woman over 18) then this group is for you!  Check out their website http://www.traildames.com or look them up at http://www.meetup.com.  There are chapters in Georgia (the original group), Virginia, Maryland and more!  Come join us!
