In the park I usually gravitate to the colonnade of pine trees planted many, many years ago. Some of the trees are now falling out of the colonnade. It's hard to avoid verticals when doing trees. John Fowles in The Tree writes that "trees warp time, or rather create a variety of times: here dense and abrupt, there calm and sinuous--never plodding, mechanical, inescapably monotonous." Except maybe in the colonnade. Time is different there, but the mechanical is also present.
