Enforcement! We need to have a greater presence to rid the parks of this vandalism and destruction of public property. We should be promoting community watch groups to take ownership of our public spaces. Likewise, expand our adopt a site to include our parks. We also need to acknowledge that we do not have local activities for our kids. I'm not talking about organized sports but private enterprise offering things like bowling, movies, rock climbing etc. It would be a win-win for the business person and the city as we have a captive audience. For those entrepreneurs out there, look at this overlooked market segment.
