Where have all the bullfrogs gone? With winter just around the corner, children will dig into the Arboretum's wetland to make some surprising discoveries. Handmade binoculars will help them with their wetland explorations.

Classes are open to children ages 3 to 5. Pre-registration is required. Enrollment is limited to 15 children, so early registration is recommended. Sessions include eight classes; all classes begin promptly at 10 a.m. The fee for a session (eight classes) is $55 for members and $65 for the general public. Each class includes a snack and a craft. Programs are led by popular children's teacher Jenny Houghton.
