Plan Your Visit

Plan to spend at least an hour at CMMC. When you first arrive, watch our introductory video: "Chatham Radio: WCC The Untold Story", narrated by Walter Cronkite. We have additional short videos that will enhance your visit -- each is about 10 minutes long (see our Exhibits page for their description).

Take time to explore. Depending upon your interests, you may find that you want several hours, or to take advantage of your free second-visit opportunity.

Most of our exhibits have "touch screen" panels and audio to provide background information. You can send a message in Morse code at the interactive kiosk. Children will enjoy the scavenger hunt to identify items across the exhibit space.

Spend some time in the Museum Shop, browsing the wide selection of books, logo clothing and other items.
