Here are the locations T.E.D.D mentions on his route. (Sorry if I've missed any)
I had typed these out in full with description and more in depth explanation of the descriptions, but lost it when my browser faffed up so I've just written this as simple as possible.
I've looked at different possibilities for each place, some have more history than others but I've only written the links to nuclear power/weapons and aliens, as this seems to be the most common occurence but there was quite a few links to chemical and biological weapons testing aswell.
Greenbrier Resort - Nuclear Bunker
Bohemian Grove - Apparently the the Manhatten project was planned here.
Tehachapi Ranch - Also know as the northrop facility, this has all sorts of links to the development of Nuclear weapons (and aliens)
Grand Central Station - The granite the station is made of gives off more radiation that is allowed from a nuclear reactor. (I think theres more to this one though)
