Bridges. Sometimes you have to cross them and sometimes you have to burn them. And sometimes you have to photograph them. This one looks pretty sturdy, although not all of them do. Bridges span gaps and bring things that seem dissimilar together. They have lots of uses both literally and figuratively.
Maybe we should spend more time building bridges to help us cross into new territory and burn the ones that allow the shadows of the past to follow us. Maybe we need to see where they go or stand on them and watch the river flow past below.
