If you're planning to be near Wall SD check out the Missileman site on the web and set up an appointment for a free tour of the site led by a Ranger. They take groups of 6 down into the underground control area then to the launch site. Very interesting and everything is as they left it in the '60s. The armored car cost $65,000 back then, windows could not be opened and there was NO airconditioning! Imagine sitting in that in SD summertime :shock:
