for me, it started on a vacation to mexico.. slept in a mayan (Hammock!!) in this little hotel in the middle of the jungle down by the Guatemalan border.. I loved it.. but I never really thought it was feasible for camping until years later I was in the mountains, and came across someone using a HH..
It took all of one night of me with roots and rocks in my back to realize the guy with the hammock was a genius
I've never slept on the ground since
