Hmm. I do actually use a park. I use the park four or five times day walking my dog. Now I can only speak for Dexter Park as that is the park I use.
But, a lot of people actually use the park in this way too. I pick up after my dog, and a lot of other people. In fact I bought a pair of gloves expressly for this purpose. I am a one main chain gang, picking up litter.
Obviously I feel a sense of ownership for the park. My dog loves it and so do I. And I dont need soccer fields to feel this way. A lot of people walk their dog in Dexter Park and almost all of them pick up after themselves and pick up other people's litter.
Soccer is also played in the park during the warm months with makeshifts goals made by the players. They almost never pick up after themselves. T-shirts, gatorade bottles and other stuff is routinely left. Plus, the area where they play is totally worn down to the dirt. I highly doubt that making a real field is going to magically change they way a lot of the soccer player's treat their park. Trash will just be left on nicer fields.
Dexter park also has a nice playground, used everyday by neighborhood kids. The kids and their parents pick up better than the soccer player's. They care about their playground.
Nothing in the park is maintained properly by the city. Yet there are groups of users who care enough to maintain it for themselves and others. There are also a group of users who do not. Rewarding them with better fields is fine, maybe they will care more. But the people who do use the park and care about it should be rewarded with a better maintained playground and a nice dog park once the legalities are worked out before putting up soccer fields.
Alright, rant over.
