Hemlock Bluffs Nature Preserve in Cary. We picked up a pamphlet that had a paragraph about the park for each of the 30 markers along both trails there.
We talked about the lifecycles in the forest, how trees grow and fall down and how insects, birds and mammals can make their homes in the trees.
We saw a HUGE grey spider in the hollow of a tree. I'd guess it was at least six inches across easily.
All in all a good walk. Now to go have some dinner.
