Yeah, you're echoing my thoughts. I bet the number is pretty significant, though. The old trident philosophy would have split available warheads into land, sea and air-based contingents, and the land - based ones are largely in this area. Western South Dakota, eastern Montana, Wyoming and eastern Colorado are home to thousands of nukes. There are MX missiles running around from launch site to launch site on underground railroads, and fixed launch locations by the hundreds; all sorts of stuff we never hear about.
<edit>
I just looked at the Wikipedia entry on mx missiles. According to that, the last ones at Warren were decommisioned a couple of years ago. There are still the Minutemen, but the mx's are gone. Or so says Wikipedia. The minuteman entry says they've been (or are being) reconfigured to only carry a single warhead. So the total number of warheads must have decreased from somewhere around 2000 (10 per mx, 3 per minuteman) to 500 or so. I feel better.
