We all do stupid things at times and I recently did mine. My wife and I had to take a trip to Utah to see one of our children. Because our car is on the small size and we were taking quite a bit of stuff for them, I had to make some extra room in the car. So I set aside a few things that I normally carry, including a set of jumper cables.
You guessed it; I had a dead battery on the trip and no jumper cables. Fortunately, I was able to get help and got started without any problem. A new battery and a set of jumper cables later my problem is solved. But it goes to show you always need to be careful.
If you don’t have a set of jumper cables and know how to use them, get a set and learn to use them now. My mistake was harmless, it just cost us a little time, but in a real emergency it could have been fatal.
