What is the relationship between the first picture and the second one? Love is the answer. Our couple overlooking the Bug Lighthouse seem romantically inclined. And the second picture shows the Portland, Maine Love Locks Wall - where couples 'lock in their love'. It started in 2013 on Valentine's Day and has increased since then - so substantially that the fence has structural problems from the weight and started to come apart. When we were there, the fence is cordoned off. The full story from July 2016 is here talking about the plans to move it, etc.
