#6 Free Air
I was going on a road trip. We packed everything in the trunk. Then, I realized that I forgot to check the air in the spare tire. Faced with unpacking and then repacking, I thought: “What are the odds? We’ve had the car for years, never had a flat, and we probably won’t have a flat now.” Then I thought, “Forget that,” and tossed the floor pump I use for my bicycle into the trunk, just in case.
We ended up getting a flat in the middle of freaking nowhere. The spare was too flat to drive on. The floor pump saved my butt. It gets packed on every trip now.
