Join AAron Capouellez of PA Woods and Forests for a twilight frog walk at the Otto and Magdalene Ackermann Nature Preserve in North Huntingdon Township.  The vegetated floodplain of this preserve is home to many native amphibians, and spring is when you can hear them best.  This guided walk will be slow-paced, but will involve clambering down some steep sections of trail. Please wear sturdy waterproof shoes and bring a flashlight or headlamp.
