I don't disagree with you, but I think it depends on the age group you look at. The younger ones love the team sports and learn lots of good things attending these programs. They might be there initially because their parent thought it was a good idea, but most of them do really enjoy it once they are introduced to it. I think a majority of these younger kids would say they want the fields (or a playground if they are younger than 4th grade).
I am by no means a team sports cheerleader, but in addition to the obvious benefit of the children learning a sport and how to work with a team, I've seen the team sports help build the community. Families connect with one another and work together to grow the area. Everyone sees a different need and will find people that have the same interest in building that aspect of the community. One of the reasons Mission Playpark! was created was to help build this sense of community with the families that have kids that aren't yet in school. There just isn't a place for moms (usually) and their small children to meet and get to know one another and form a community to support one another.
If you go to the fields that are used for soccer, during soccer season, you'll see that they are packed and creative scheduling is happening. Same is true for football, baseball and softball. It is frustrating that the fields aren't being used all year round, but as the sport season changes, the fields in season are packed. Trying to use multisport fields will help with this. As the kids get older, they will play the sports that they truly enjoy, not what their parents enjoy, so the numbers go down. I've seen this with my kids as they stop doing the sports they were doing to be part of the fun, and instead concentrate on those sports that they really, really enjoy and start to excel in. Skate boarding is one sport I've seen the 5th -8th graders move to (along with surfing!). I'm sure they started younger, but they really get a passion for it in the middle school ages.
As I said in my previous post, I do agree that that older kids want and need a place to skate. Many of the older kids have moved on from team sports and found that they love to skate and want a great place to do it without getting hassled. A large percentage of them will vote for a skate park. I totally support this and hope that the county and those that want to get involved are successful in getting all the recreational facilities we need for all ages. The more people there are asking for recreational facilities for the families in the area, the better.
