Help, please. I will be driving down I5 from Seattle soon and would like to find this interpretive center in Clackamas. I will be stopping in Milwaukie to visit the Willsburg train station and the Willsburg Cemetery (from the bygone town of Willsburg which was named for my g.g.g.g.grandparents, George Jacob Wills and Sarah Jane Moore Wills). Would one of you give me directions for finding the interpretive center from 205? Thanks. Lois in sunny and HOT CA
