My wife and I made love out in the open at midday on a large flat rock in a National Park meadow. It was perfect weather and a perfect setting to take a break from hiking and make love. No one saw us; we were off the trail. Now, we can't find our "love rock." There must be millions of couples who have made love out in the open like that in daylight in a National Park. It's is probably illegal, but I have never heard of anyone getting arrested for doing it.
