I was going to walk the Swamp Boardwalk, only on the hill up toward it (it goes up, then back down to the swamp), I saw that the boardwalk had sunk halfway along the path. So I took an alternate path that had a steep climb (for me) and got around to one of the main paths. It was very pleasant.
Along with the spring flowers that I saw on my walk, I've just finished reading The Secret Garden for the first time. :-)
