Ten pre-registered pre-schoolers ages 3-5 and parents can join the Knee-High Naturalist Program at the Eagle River Center for guided nature exploration.  The program runs on Saturdays in October.   Dress for the outdoors, and bring a snack or lunch to join fellow Kneehighs after the program.  Crafts and toys are available during the half-hour before the program starts.  Limited to 10 children (minimum of 5; no walk-ins allowed). Younger siblings are welcome, but need to register and pay (if 2 years or older) to participate.  Not open to school-aged children.  Call 694-2108 to register.
