On Monday, June 19, about 5:30 p.m., I was driving west on Interstate 84. I was about an eighth of a mile from the Exit 5 ramp when I heard a very strange sound, sort of like a piece of cardboard caught under my car and dragging on the roadway.

I pulled over at the ramp. It was a flat tire.

Never having changed a tire, I was standing by my car reading the owner's manual. I thought, "How difficult can this be? People have flat tires all the time."

I had just figured out where the spare was and the thing under the spare had to be the jack. Just at that moment a car pulled up, a young couple got out and within minutes had changed my tire.

They were absolutely terrific, and I thank them very much.
