Mountain View, California
Almost got busted for this one.
This was not too far off of a public biking trail. It took awhile to find a good spot at this dried-up slough, but luckily my buddy Steve came with me and we were able to cover extra ground. After trying out several compositions, what looked like a police officer and a ranger (maybe they were just security?) came hiking out to where we were. They asked for our IDs; like an idiot, I left mine in the car. They wanted to know what we were doing out there and if we knew where we were.
It seemed like their biggest concern was that we were not photographing the buildings nearby, which makes sense since a military base (Moffett Field), NASA Ames Research Center, and Lockhead Martin (not to mention Google) are nearby.
Although the police officer insisted on looking at the pictures that I took, he was a pretty nice guy. I was so nervous about being questioned, that I couldn't figure out how to show him the pictures I had taken. Turned out the button on my wired remote was still depressed (duh!), so the camera wouldn't allow me to do anything and it just...kept...on...taking...pictures...
The other guy, grumbled into his walkie-talkie (with a touch of exasperation), "they're just taking pictures..."
The one time Steve got the wife's permission to come out and this happens...too funny...
