It is obvious that a lighthouse is a beacon for discerning the edge of land as seen from the water. My feeling is that on average we don't experience lighthouses in the same manner now that navigation is on a screen and long distance travel for passengers is primarily in the air. Lighthouses have become more like family photo-op destinations with an attractive, somewhat romanticized, technological artifact. At no time have I been crossing a body of water and felt the relief of seeing a lighthouse. However, I have stood on the shore and looked out at the vast ocean and felt the unknown immensity. Consider looking from the parking lot side and invert the standard metaphor: "a lighthouse is a beacon indicating the end of something (the known) and the beginning of the unknown vastness." Thus, "Lighthouse," is a warning sign or a welcome sign that nothing is ahead.
