I think it's particularly a distinctively American concept that resonates with American culture through biker culture. A motorcycle is an independent thing. You're like 'I don't want to ride in a car with this person. I want to be independent and ride by myself. But let's ride in a group. Let's be independent together.'
Despite the demands of this job one of the things my wife and I try to do is to spend time together alone. And one of the things we really enjoy doing together is seeing a good movie.
