  2. Michelle,

    We are excited to hear about your interest in our Home School Day in May!

    Currently, we are organzing this event and will make the information available through this website when we are closer to May.

    This event is titled “The Corps vs. the River” which includes presenters from the U.S. Army Corps of Engineers discussing their jobs as engineers and how they deal the Mississippi River.

    We are interested in creating more events for Home School Groups so please give us feedback on what you all would like to see more of in the future!

    Merry Christmas,
    Kathleen Mocklin,M.A.
