The header above is the saddest epitath I've ever seen.
My wife and I were 39 and 43, respectively, in 1989 when we decided to hike the AT.
At the time we were living on our boat in Fla. We quit our jobs, put the boat into try storage and took off. My hiking experience was very limited, a couple of week long trips "car camping' and a few overnighters. My wife had done 250 mi of the AT a few years earlier.
When we hit Neel Gap, we sent back aprox 25 lb of stuff we didn't need or couldn't use and I had to buy a new pair of boots because the ones I purchased in "civilization" were useless and incorrectly fitted. We had the wrong mid layer clothing & many other thing that we thought were wonderful, again for car camping, but were not working for us on the trail.
By the time we got to Duncannan, we had replaced, our tent, both our backpacks, water filter and both of us had gone through 2 pairs of boots.
Our experiences, the people and places we met and saw, during our thru hike will remain with us the rest of our lives.
You'll make mistakes, your friends will question your judgment, your family will think you've lost your mind.
I was downsized last Aug, and as soon as we can sell our house we'll be back on the trail!
Just do it!
