Let's see. I used to try and find places like this on purpose...
In a car on an overpass over I85 at 11:45 on New Years Eve
In her room during the Super Bowl with her door open (when she lived with her parents... we had to keep yelling to her parents what the score was so they wouldn't come looking for us
)
Picnic table in the park during the day
Back row of a movie theater (watching A Bug's Life)
Friend's bathroom floor during a party (people just wouldn't stop knocking, I swear)
Bottom bunk (while another person was on the top bunk)
Jet Ski
On the beach (Mexico)
That's all I can come up with right now... sorry.
