Redhill Bowl Park off Lawrence. Park, walk through the tunnel. Lots of private places lining the ball diamonds to put down a blanket after dark. You can see people enter the park but they can't see you till their eyes adjust to the light. When we go there, we send a quick phone light flash to let potentials know there is someone there. If they know what's going on, they usually casually make their way in our direction... and then we go from there. It's not a popular place, so letting people know you are going in advance is crucial or you will more than likely just be having fun without "witnesses"
