Remaining Communities

We performed a spatial overlay between US Census's Incorporated Places dataset and all the city / town hall features collected to date. We then limited the results to communities with a population greater than 600 since larger communities are more likely to have their own designated city hall. The results reveal a few incorporated places that do not yet have a city/town hall point inside their boundaries but may be large enough to support such a structure; the map below highlights these communities.   

NOTE that this does not mean every one of these communities is missing a point.  It is possible that some of these communities do not have a building that fits our definition of a city / town hall while others may have already been collected but their city / town hall falls outside their corporate boundary.  

Please help us research these communities and determine if a city / town hall exists!
