The DPM in Aberdeen is a look at the history of Brown County and how westward expansion of the U.S. formed our region, culturally and economically. Explore the history of the railroad and pioneer settlers; a children’s exhibit allows families to experience frontier life; the Hatterscheidt Wildlife Gallery is an exciting departure into Africa, Asia and North America. Take home a memento from our gift shop. We’re open 9 a.m.-5 p.m., Tuesday-Friday, and 1-4 p.m., Saturday-Sunday. Admission is free.
