I just finished posting my Ottawa, Kansas trip from January. I ended up with 65 waymarks and two visits. Highlights include completing all of the buildings in the Historic Downtown District, a former Carnegie Library, and a Tribal flag for the Ottawa tribe:
Elks Building in the Ottawa Downtown Historic District
Former Carnegie Library - now a Community Center
Ottawa Tribal Flag - this flag is on the Ottawa
University Campus. The University was originally
built to provide education for the Tribe's children.
