I was concerned about the same thing. I've been planning for months and had no one to travel with except my dog. Everything I've research says the same thing, "Don't worry about it". Thiis is my first thru hike and I'm actually going to take the advice of the experienced hikers. Hopefully there will be plenty of folks that I can travel with along the way. I'm looking at this as two adventure in one; the hike itself and meeting my new friends. I hope this will help you in knowing that you aren't alone in your feeling.
