Open sex

Is there any place where people can have sex openly in natures lap without geting disturbed?

well me and my boyfriend had it at the park on the slide and on the swing set I sat on his lap and he gave it too me really good.
I have even done it at a football game, well all of our friends surrounded us behind the bleachers but damn it worked good.

My back yard is great and private. If anyone sees us its because they wanted to. Don't care who is watching at that point.
