For myself,
Getting away from it all . . even though I live in a fairly peaceful village
Feeling as though I'm places man hasn't touched, or at least spoiled
Not having to stick to a schedule of destination or stop
Feeling the awesomeness of pure nature and its sounds and smells
Experiencing an old way of 'tramping' life . . freedom to roam
Having the time to notice detailed beauty of my surroundings
Appreciating how beautiful the world can be when I just 'be'
Being happy with minimal comforts
Looking forward to seeing my family again
