What was so interesting?
Might drive by and get that photo you missed, if it's really something.
I'm in the area, too.
You sure your not just thinking about microwave communication dish farms up there.
Not exactly FTA, but have you seen the dish farm at the intersection of Via Oro Ave. and Hughes Way (right next to the 710/405 interchange)? I think it's one of the uplinks for 123W. Among other things they have a 25m toroidal with 15 or so LNBs on it. It's right next to the street so it should make for some good photos (if it weren't such a long drive for me I'd do it myself).
Yep, that's the one! I think gillham is right about its purpose: the two big dishes look like they're pointed at 95W.
