A man decided that he was going to ride a road bike from Phoenix to Flagstaff. He got as far as Black Canyon City before the mountains just became too much and he could go no farther. He stuck his thumb out but after 3 hours, hadn't gotten a single person to stop. Finally, a guy in a Porsche pulled over and offered him a ride. Of course, the bike wouldn't fit in the car. The owner of the Porsche found a piece of rope lying by the highway and tied it to his bumper. He tied the other end to the bike and told the man that if he got to going too fast, to honk the horn on his bike and that he would slow down. Everything went fine for the first 30 miles. Suddenly, another Porsche blew past them. Forgetting completely about the cyclist he's towing, the Porsche pulling the bike immediately took off after the other. A short distance down the road, the Porsches, both going well over 90 mph, blew through a speed trap. The police officer noted the speeds from his radar gun and radioed to the other officer that he had 2 Porsches headed his way at over 90 mph. He then delayed, "And you're not going to believe this, but there's this REALLY amazing guy on a road bike honking to pass!"
