Naturalist Jessica Miller will lead a walk up to the top of Mosquito Hill offering participants a chance to enjoy fall at its finest. Take part in some activities that will help you understand the change of the seasons: why leaves change color, how plants and animals prepare for the onset of winter, and more. Cost: $6 per person or $10 per family. Call 920-779-6433 or e-mail mary.swifka@outagamie.org to register before Oct. 20.
