That I've met? Probably my grandfather. That was the hardest man I've ever known. Just as an example, one time he took my brother and I, I must have been 13 or 14, to Tallulah Gorge on a day trip and we started looking around for places to hike down to the one of the areas that's more off the map, so there wouldn't be as many people around and we could enjoy it a bit more. Now keep in mind this man was 87 at the time. After somewhat intentionally missing several "No hiking beyong this point" signs posted here and there, we find an out of the way spot and start making our way down. Now this was not a gentle path, it was more a deer trail and there were several points where we were hanging onto trees to keep from sliding down the incline. We finally get down to the bottom and we're poking around and having a good old time, when one of the park rangers walks out of the bush and calls us over. Apparently that sign we ... um ... somehow missed ... yea ... was essentially a no tresspassing sign.
Mr. Park Ranger informed us that the area we were in was off limits due to safety issues, that by being there we could be arrested for tresspasing on federal property, and how, pray tell, did we get down without seeing the multiple signs posted? After describing where we were parked and what path we had taken, the Ranger takes off his hat, scratches his head a bit, looks up at where we had come from, looks back down at my grandfather and asks him "Sir, may I ask how old you are?" My grandad tells him and the Ranger chuckled for a minute before telling us "I don't think I could have made that path, and I sure hope I'm half as fit as you are when I get to be that age." then escorts us up a somewhat easier trail back to the car and tells us to be on our way. It was at that point, where I realized that my 87 year old grandfather has just hiked us down to commit federal tresspass, a path that a Park Ranger considered too difficult for himself, simply because he thought it might be nice, and then somehow managed to not get us arrested when we got busted - that was the point where I started holding that man in awe.
