I love living in a basically free society where people can fell free to do, for the most part, what they want. People also have the choice to participate in activities of their choosing. Business people also have the freedom to offer products and services of their choosing.
As a field owner, I will never allow people to shoot that much paint. But other field owners can offer that type of play to people if they feel there is a market for it. It's good to live in a free society.
