Clear Prop!

Dr. Ken told me about passing a Chevy Suburban on the highway. It was towing a boat with an outboard motor. The motor was obviously in neutral because the propeller was spinning like crazy from the slip-stream under the car. I turned to my wife, pointed to the boat, and said, tongue-in-cheek, "Look, that's a good idea. Those Suburbans are heavy and burn a lot of gas so this guy started his boat motor so the propeller will help PUSH him!" My wife, said, in all seriousness, "Wow, that *is* a good idea. I wonder why more folks don't do that."
