Rocky, you make it sound like you have to be Indiana Jones to get there

It's not nearly that bad... the walk from Torrey Pines is flat and maybe 10 minutes if I remember right, and I agree that the path from the cliffs is tiring, but not particularly dangerous.

But... were you being facetious about easy surveillance? You could certainly keep track visually, but unless there are parabolic microphones with really long range, I don't know how you'd be able to track conversation.

As an aside, I'm guessing the police handling the surveillance were underwhelmed at having to watch Harlow and Sean (and perhaps Grant and Joseph) cavort naked on the beach... they probably had to go and watch straight porn that night to get rid of the images in their heads
