My biggest ongoing project is to take at least one photograph of each town and village in my area (west-central Indiana) to complement the corresponding articles in Wikipedia. Historical sites and markers, short-line railroads, local flora and fauna, etc. also invariably make me reach for my Canon.

I release all my Wikimedia Commons photos into the public domain, so feel free to use them as you please. If out of the goodness of your heart you'd like to give me a photographic credit, my name is Huw Williams.
