Hamlin County, South Dakota - Wikipedia, the free encyclopedia
There's a start for factual information.
You may want to see if you can get in contact with a county Chamber of Commerce.
I wouldn't expect it to be developed much at all, with a population of just over 5,000.
You within probably within 2 hours of either Aberdeen and Sioux Falls. Watertown is relatively close also.
There seems to be a handfull of lakes in Hamlin County.
Google Maps and type in Hayti SD. Hayti is the county seat of Hamilin County.
I wish the the best of luck in your travels.
