Five elementary teachers took 100 students on field trips to Oceano State Park off Pier Avenue for a nature walk around the lagoon, an enchanting and educationally valuable site. Its Nature Center claims to provide educational tours. Unfortunately, we discovered the Nature Center is open only one day a week and no one is ever available for tours. A ranger told me there are not enough of them: The few rangers assigned to the area are too busy with law enforcement. I know they are enforcing, or at least trying to, the law along the beach and in the off-road vehicles area. We had to walk around the lagoon on our own and do the best we could with the whale display, the ducks, and the native gardens. Finally, we wanted to picnic and play at the Oceano playground, a few hundred yards from the park, but across the street. We were aghast not to find a single pedestrian crossing along Pier Avenue, except at the light on the highway, a too long and perilous walk for 40 hungry second graders. Hundreds of vehicles speed along Pier Avenue in both directions. We need a pedestrian crossway on Pier Avenue for our safety. We need to have rangers available to educate our children. The so-called recreational off-road area is sucking our resources but giving nothing back to the Oceano community. It is time to shut it down.
