What's the weirdest place you had sex??

So my bf and I went to a football game and we left a little early so we can spend time alone. Well he didn't want to go home so we went to the park down from both of our houses and we started to make out and thing got a little crazy. We didn't have sex at the park. I was worried someone was going to see us or hear us. So have any of y'all had sex (or close to it) somewhere other then at home?
