When I was a kid, my mother and I used to go out trail riding on some state park land that was 20 or 30 miles from home. So we would put her horse and my pony on the trailer and drive down there and find a good spot to park with easy trail access.
This was long before the days of cell phones or GPS or any of those modern miracles. So we would go out with the paper map of the trail system in our pockets and hopefully end up an hour or two later back where we had left the truck and trailer parked. Lol.
I remember my mother always had a saddle bag with a few different odds and ends in it, including some baling twine. Each horse would also wear a halter over the bridle with a lead rope tied around its neck.
And my mother would always have a whistle and a jackknife in her pocket, just in case. We had tons of fun. Those were the days.
