"Serrano Point is supposed to be located in Avila Beach in California I believe. According to this site:
http://terminator.wikia.com/wiki/Serrano_Point_Nuclear_Power_Plant

Also there really is a missile testing range in Topanga Canyon. However, from my research it is not consistent with the locations of the actual Topanga Canyon (I think the missile range was in the city while the actual Canyon is located outside the city or something along those lines). I was slightly confused by that.

"I want to point out that all those bases are probably targeted by Russian missiles. Area 51, Edwards, Ft. Irwin may be away from big cities, but will still be targeted.

Unless Skynet can h4x attack the Russian launch computers or take control of missiles and redirect them away from military bases to cities."

"wait would Russia really target Area 51, it's in the middle of Nevada, in a dessert, the middle of nowhere. Then again it depends on how many nukes Russia has to dump on the US :P"

"In the Cold War Area 51 was a testing grounds, so yeah, I'd think they'd target it.

I guess Skynet could shoot down missiles. Maybe it somehow uses some nukes as a nuclear ABM shield like the one around Moscow?"

"It would also depend if Skynet deems Area 51 worthy of saving, like if it had some UAV, H/K, Terminator, or future weapon prototypes Skynet might save it.

it all depends, we don't exactly know how a defense A.I. thinks"
