eburg, thanks for the update about the GSB cam back on live. Speculation, about why it was down: In the Giving Tuesday presentation, John & Amy talked about adding a camera to the "far side" of the cliff so that we can see what's going on there. Perhaps they were installing the new equipment. Feel free to chime in if anyone has more accurate info.
I like watching GSB for all of the various activities, too. Mostly the peregrines, of course. Last season was the best since I've been watching this location, 5 years or so.
