At the park today and noticed this.

This is a small fenced area surrounding a patch of Wolfsbane.. it's highly toxic to animals and people, it cropped up a couple of years ago as a small plant.. at first it was relatively unnoticed, last year it had spread out a bit and they put up a warning sign but it keeps spreading.. there are now two fenced patches near the lower parking area..
They took the sign down though.. some silly person will probably reach in and pick the pretty flowers and then wonder why they got so sick tomorrow..
