I was fishing and camping in the Brooks Reserve in Katmai Alaska.
The Bears there are like the Deer around here. The Federal park Rangers have a full time job
keeping humans away from the Bears so they do not get accustomed being around humans and so they don't look for food from them.
Because of this they are always patrolling the rivers banks with their walkie talkies herding the few fishermen around the bears.
So I'm fishing in the river next to another guy, we are looking at Salmon so thick you could of walked across the river on their backs and not get wet. Unfortunately that does not mean they are easy to catch!
Well the guy next to me finally hooks one and the fight is on. Just then a Ranger comes around the corner and says that there are Bears coming our way and we need to move. The Rangers do this because the Bears know if they see a guy fighting a fish it will soon be lunch time. Well the guy with the fish on doesn't want to move. The Ranger asks him again to break off the fish and move down stream. The guy says I'll have this fish landed in a minute just wait. The Ranger puts one hand on his large nickel plated pistol and with the other pulls out a switchblade and cuts the guys line.
Then he says you just lost that fish...anything else you want to loose?
I was having a hard time believing the fisherman was giving one of these giant of a man Ranger guy a hard time. They all had the personalty of a fire hydrant
and where twice as tough. This reserve is like 200,000 square miles in size. It would be easy to off someone and nobody but the Bears would know
Ok I know this is not exactly a nature thing, but I was fishing at the time.
