That's not good Margery. Arnie never pulls anything anymore. He used to pull the bike and me on skiis, but now he is very good about sticking by me when running or sliing, so does not need a leash. In a city parade it was necessary. The problem with racing is the financial incentive of fame maybe? once again the bottomline tops quality of life. It's a modern epidemic of greed that seems to be used as an excuse for cruelty on a worldwide truly massive scale. human empire preys upon life itself.
