While some see winter as a time of hibernation, those involved with the McHenry County Conservation District see the season as an opportunity for outdoor exploration. And they’d like you to join them, either at an event or as a volunteer. “The more volunteers we have, the more we can do,” said Lora Petrak, community relations specialist for the district, which owns or manages nearly 25,600 acres of open land diverse with woodlands, prairies, wetlands, ponds, creeks and more. In what looks to become an annual event, the district is hosting a Volunteer Fair from 11 a.m.
