Actually I decided to scratch adding tags for towers. It's too cluttered and they're easy to find anyway. I'd rather just find facilities that are away from airports including TRACONs that aren't at the base of towers.
I have all the centers besides Jacksonville, and that's only because the photo quality for that area is so low that I can't make it out. TRACONs I have are Houston, Omaha, Phoenix, Atlanta, Chicago, Potomac, Denver, SoCal, NorCal, and New York. Half of the problem is not knowing for sure which TRACONs are seperate and which are in the base of towers, though I have a decent idea on most of them.
I have the address for Seattle but when I plug it in, it's not there. Therefore I'm guessing it's just an old picture, as that facility is fairly new. Ones I know are seperate that I haven't found include Dallas and Boston Consolidated, though I'm sure there are more.
I appreciate any help.
