Thank you for the honesty :) I'm probably just trying to imagine that there's some kind of fantasy into the wild thing that in reality is very rare.
Sometimes I feel treally strong need to get away and I almost can't resist, so I usually take my bag and just wonder few days in random forests and small cities. I use train for transport to unknown destination, sometimes with ticket sometimes without (not very often, I am scared) or hitch a ride if I want to talk (not very often too).
At the beginning of each trip there is always great feeling of freedom but in few days I get bored and start to look for a way how to get home. The biggest problem is loneliness, boredom and loads of time for thinking. Weather may be problem too, but nothing that good preparation could not beat. Never had serious problem with people but I am male and usually sleep in uninhabited areas.
I am not sure about plane, but I thing getting out of routine and free yourself by this way is super idea.
Safe travels :)
