I recall an incident that happened at the horseback riding summer camp that I went to during my preteen years.
The camp operator had --in addition to two dozen young, fit and sweet-natured horses-- a truly ancient, fat and irritable mongrel pony mare. This had been her childhood pony. This pony was in retirement, none of the campers rode her. Frankly, we were all a little scared of her! Her name was Onion.
One day at camp, we saddled up the horses and went on a trail ride.
The campers were divided into two groups. The camp operator took one group on one trail, her eldest daughter (Her daughters were the closest thing that the camp had to "Camp Counselors"!) took the other group on another trail. I was in the camp operators group.
My group had a lovely trail ride, the other group didn't come back.
We gave them an hour to return, nothing. The camp operator tried calling her daughter's cell phone, no response. A thunderstorm started moving in, parents were due to start arriving to pick up their kids. The camp operator was rather frantic at this point. She couldn't leave the remaining campers, we needed adult supervision! But calling the police to launch a manhunt would effectively mean that her camp would never operate again.
All while this is going on, Onion had been pacing around her stall. She kicked the walls, jiggled the lock and periodically would look in a specific direction and let out an ear-piercing whinny.
This understandably did not soothe the camp operators nerves.
Eventually she got so sick of this that took Onion out of her stall and turned her loose onto the property! For camper safety, allowing the horses to roam the property freely wasn't typically done. But she stayed in the barn with us (The campers), thinking that Onion would find a nice spot to graze and would settle down.
Onion did not do that. She galloped straight toward the nearest gate and jumped it! I was awed, the other campers were delighted, the camp operator was horrified. Now she not only was her eldest daughter and a dozen campers missing, but her beloved childhood pony was on the loose!
Within ten minutes Onion was back. With the missing trail riders!
Nobody could believe it!
The elder daughter explained what had happened once everybody calmed down and put the horses away. The had taken several wrong turns on the trail they had gone on, ending up quite a ways away from where they were supposed to be. They had tried retracing their steps, but that only got them turned around and effectively more lost. No one's cell phones were working.
Then Onion came trotting up the trail. She had not only somehow found them, but she ended up leading them back to the camp!
None of the campers were afraid of that half blind pony after that.
