sounds like it would be fun. my wife and I have done the deed at a boat ramp several times

1. In space. We plan to go up on Virgin Galactic as a couple of tourists, but I suspect that joining the 100 mile high club won't be an option. Too many people in too small a space with zero privacy, at least for a few years.

2. DEEP underwater. We are technical divers and actually plan to try our hand at deep ocean sex this summer. Our goal is at 150 feet in the warm waters of the far east (cannot say where, sorry).

3. At the top of a SUPER high Ferris wheel. We did manage a super quickie on the observation deck of a famous "overlook tower", when it was windy, cold and we were literally the only crazy people on the outer deck. Hubby snuck up behind me, and to the world looked like he was just hugging me, but his fly was undone and his penis went well up my vagina from behind, as he had hiked my short skirt and while it appeared I had on panty hose, I really was wearing stockings and no undies. However we were worried about cameras or other visitors coming onto the deck, so the "event" lasted only about a minute!

We tried that in our youth. He slowed to about 40 on a barren stretch of interstate freeway, he was SO distracted. It was a dangerous and silly thing to do, even with no other cars around. I am just not that insane anymore.

Please let me know ahead of time and I'll steer clear of that part of the highway. Just like Bignuf said - it's a dangerous and silly thing to do!

I agree! I've surprised you didn't get into an accident!

When we did it, we were on an open stretch of rural highway (you could see about 20 miles in all directions, boring and flat as a pancake), and it was at 5 AM. on a Sunday. There was not a car to be seen during an entire hour long car ride. Even then, we took a silly risk that comes from being 20 years old. Not worth it. Very little thrill, lots of potential "cost".

The time we did it, I started by giving hubby a BJ while he was driving. He tried to pay attention to the road, but slowed from 70 to about 40 in no time. It didn't matter, since there were no other cars, and it was a straight "farmland" drive. I then actually straddled him, facing him, as he looked over my shoulder and steered with his arms around me. He tried this for about fifteen seconds before he literally hit the breaks, said "I can't drive this way". Gave me a big smile and a wet kiss for trying, and then had me get back in my seat. I guess I really was the more "crazy one" that day. Again, we were very young and yes indeed, very stupid about risk. I think that does come with youth. As they say, the "risk assessment" areas of the brain are not even fully developed till about 25. I look back at that event and while a naughty part of me still giggles about it, 99.9% of me goes, "what the heck was I thinking? It would have been FAR safer and more fun too, to stop in some small town and rent a hotel room for a couple hours"!

Mr. Bignuf chiming in. You might want to reconsider Olympus Mons dv8. While it is the highest mountain in our solar system, there is an interesting fact to consider. While mountains on earth are very "steep", due to side erosion and the upheaval forces of tectonic motion, therefore giving you that "look down, you are on a high mountain" feel, Olympus Mons is so gently sloped and so wide around, that sitting at the peak and looking all around, you would probably feel like you were on a flat (or gently sloping) plane. No sense of height or being on a mountain. The slope away is just so gradual that unlike, say Everest, where the Horizontal distance of 1000 feet can equal a vertical drop of thousands of feet, on Mars, that same horizontal 1000 feet would only equal a vertical drop of maybe ten or twelve feet! No sense of mountainside, just a most gentle slope..if anything.
