Ben of the sky is big in Pasadena posted this story about being confronted by a security guard for taking pictures of one of the lesser architectural "wonders" of Pasadena from a public place.
I dug through my messy unorganized files and found these shots of that same building. I never had trouble at that location - maybe because my pocket point and shoot is so small - but I've certainly had my encounters with people elsewhere who thought I shouldn't be taking pictures. (If you click a picture, it'll enlarge.)
This is what I call a "framing shot" - while I'm taking pictures at a location I try to find a sign to help me identify it later.
Google Street view has pictures all around this building. Start here.
Here's another picture I took of a small detail on the Green Street side of Pasadena Towers.
Here's my picture of the "Photography is prohibited" sign at Pinkberry in Old Pasadena.
