The walkindude is just a guy who likes to walk, generally a long way, away from people to the most spectacular sights.
He has started and quit several blogs in the past, probably more than the hikes he has started then quit.
He used to play video games and enjoy the indoor life but then a mixture of life and stress drove him outside to the places he finds peace!
Now many years later he no longer just walks, he rafts, floats, rides, and generally enjoys most forms of human-powered transportation.
