{NSFW} Sex outdoors?

This is really not a smutty question! Rather it is a desperate plea for help!~ I am looking for ideas for places to have sex outdoors!

I ask, since the other day, my SO was filming me doing a knicker flash while I was getting out of the car. (I got in and out of the car a few times, so that he could get good footage). Further bracket (and no I have not lost my mind!).

The cops turned up and warned us. I went home shamefaced. Apparently a file was opened and now British Intelligence has me on file? Gosh, that really shows how unintelligent they are.

I did not realize that there were cameras all over the deserted parking lot and we were giving the cops a good old show.

The woods seem dodgy as the trees could have children and well, regular folk appearing from behind them, not good! The parks are also dodgy due to cameras. Help! Where does one go for outdoor sex?
