"Marc & Millie Travel the U.S." is a comprehensive unit on the 6 regions of the U.S. Each region will be available individually as they are finished throughout the year. They will eventually be bundled into one unit. Each regional unit will have details of its particular states including state flag, state bird, state flower, state coin, & sites to see. I will be using real photos of sites. I will also be making a 5 region & 4 region option.
