I lived in New York City for 5 years. I loved it. I didn't own a car. I took the subway, cabs, trains, and planes everywhere. But, I didn't go camping or own a boat. I live in South Carolina now where I tow my catamaran to different regattas or just to the beach for fun. I go camping with an amount of gear that would be completely unreasonable to take on a train. Public transportation does not allow for the same activities as a car or truck. That's just obviously true. I'd be happy to give up my car. I would not give up sailing or the type of camping I do. People that hunt, should they give up hunting because they can't transport their game? How are contractors going to get equipment to the worksite? Cars/trucks/vehicles are not just for moving people.
