A "Save the Day" tool

Today I had a dreaded happening happen. My car died in a parking garage. I called a neighbor to take the dogs home and AAA to help with the car. My neighbor who is now my hero, had jumper cables which he used to get my battery going. I thought it was a little car computer glitch because nothing was left on to have drained the battery. At any rate, I cancelled AAA and all was well. HOWEVER, it was a good lesson for me to have jumper cables in my car at all times, just in case. Sam's Club had the charging gadget which lives in the garage which I bought. Tomorrow I'll find the cables. Mercy....
