Sex in unusual places!

I went camping at the weekend with my OH and needless to say that the thought of people being able to hear us or see silohettes made me so incredibly horny I couldn't help my self, I was like a wild freakin animal!! We did it every which way and it was fantastic and it felt so naughty.

Heres the question...do you in the OA have any favourite unusual places that make you just lose control? Share the fond memories or recommendations :D
