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.
