The Centers of the USA is available for viewing by the public 24/7. A phone number on the door tells people where to call to get the access code for the keypad lock on the door, a technique used at several other exhibit facilities operated by the CLUI. The trailer, which has also been enjoyed as a shelter by members of the local highway department, has been visited by hundreds of people passing through over the last six months. Though the site is in a sense a historic relic, as it is the center just of the 48 contiguous states, it is a popular spot for people trying to get to the heart of things.
The exhibit depicts and describes several of the 'Centers' of the nation, such as the geodetic center, in Lucas, Kansas and the geographic center, near Belle Fourche, South Dakota.
