Favorite place you've had sex?

I was in Hawaii for two weeks without me SO and out of the year and a half we've been together, that's the longest we've been way from each other. So he picked me up at the airport last night and we had to pull over twice for sex. And then when we got home we had sex and then once more this morning. Talk about a wild ride! Do you have a favorite place or sex story? We loooove car sex. I guess "I miss you" sex is our favorite too.
