^the only reasonable explanation to not want to share/help in finding a spot is if it's "your" spot that you don't want to be blown out, or possibly out of respect to people that go there and skate it.
Seeing spots in videos clearly makes a spot more attractive, even if it is just another bench or picnic table. It's part of skating brochacho, skateboarding tourism; we relate to what we see. I don't think anyone would say, "why did you want to go to the brooklyn banks? there's banks at every park that are way better and smoother and easier to skate." not comparing the "iconic-ness" of the banks to this school, but those benches actually are pretty damn smooth.
And yes, the spot is in Oxnard. fact. I forget the name of the school though.
