If I had one wish that could only be something transient and tiny, it might be to swim in the Hearst Castle pools.

Okay, it wouldn’t actually be that, but it would be amazing to be in that water.
No, it would not. “that water” is chilly and oily. And seriously, this is a pretty easy wish. The security there in the 90s was crappy. I doubt it is much better now.
I still have the pictures, although something else that was crappy in the 90s was cheap cameras. We did not have a good one, because getting caught was something we had planned for.
