On the 2/11/09 episode of Law&Order, the young woman's hospital room had a large color photograph featuring both Grand Haven lighthouses. Why an "allegedly" New York City hospital would have such a photo beats me?

On the 2/3/09 episode of Fringe (a new favorite of mine), in Olivia Dunham's home was visible a print of the Edward Hopper painting of Portland Head lighthouse.

Sorry that these weren't the real lighthouses, but I thought it was pretty cool.
