Wow, never thought to list them:
1. Movie theater
2. In front seat of car in mall parking lot
3. In the window of the Marriott on 45S (third floor). Valets enjoyed the show.
4. Park and ride bench (thumbs up from HPD officer we passed when leaving)
5. Parks
6. Hotel swimming pool
7. Hotel room with slightly large crack in curtain
8. Swinger bar and house parties
9. Couples theater
...
The little lady I was with loved being watched, and I just don't care. I would definitely think twice nowadays, because a lot of people would not interrupt you, but post the video on the internet.
If you want to be watched and avoid getting arrested, go to an on-premise swinger's club or couples theater on Saturday night.
