when i was about 8 or 9, my dad and i used to love going hiking together (he's just too old for adventures now). at that point we lived in the panhandle of WV. i was too young to remember where exactly we were. we were hiking on pretty clear paths, we came across a somewhat elderly man, just sitting on a lawn chair in the brush. eyes closed, hands folded. my dad and i were somewhat spooked, it looked really strange. but when the guy heard our footsteps he looked over at us, said hello to us and said he was out enjoying God's kingdom...he went on to tell us about how he loves spending time in nature because he said "I can witness the work of God out here"
more recently, my friends and i have come across alot of really cool stuff back at frick's lock, PA...a small abandoned town near me. stuff like an old busted typewriter, household appliances, books, so on, so forth.
as much as i would love to have a few souvenirs from the place i was raised under the old "take only pictures, leave only footprints" ideal. if you respect these types of places and follow that mantra, chances are higher that people will continue being allowed there. Frick's Lock is to this day getting hit hard by vandals and disrespectful kids. as a result, you will be escorted away from there if they find you.
