How dow we handle non-mapped subsets of places?

For example, white crappie is best caught in "Tidal Chickahominy and its tributaries" and in "tidal James." We have GNIS IDs for the Chickahominy and the James, but we have no machine-readable representation of "tidal" or "and its tributaries."

The good news is that this isn't about regulation—it's about providing fishing suggestions. So a lack of precision as machine-readable data isn't legally problematic.

At the moment, I'm retaining "Tidal" in the title, but putting "and its tributaries" in a comment field. Why? I'm...well, I'm not really sure. Rough consensus, running code.
