sure

the wife and I had sex in our towns park over 26 years ago when we were young and dumb

I never have...but I've always wanted to try being the one doing it, myself. The closest I've gotten to that, was a couple of times on his apartment balcony in broad daylight--one time, wearing nothing but handcuffs! I have no idea if we were spotted, but we could have been from the nearby apartment complexes. Apparently he sunbathes nude out there all the time, and I got used to sitting out there in my underwear. It's fun.

i have see it

In the car at the drive-in and once in the middle of a campus quad.

Never seen it
