GIS - Geographic Information System.
Ever heard of it? Neither had I. There are a lot of things I didn't know about local government until I started doing a series for the newspaper I work for on Lincoln County Local Government.
I have to admit, it didn't sound like an enthralling subject matter. One thing I didn't take into account, however, was that passionate people can make just about anything interesting.
Who knew a deeper study of GIS would reveal a connection to Star Trek and visual art.
