WOODFORD - In its infant stages more than 20 years ago, the annual Earth Day event for fifth-grade students from Lafayette County schools was held at different venues each year. That was before a group of dedicated Woodford-area residents spent several years restoring Blackhawk Memorial Park, now one of the most stunningly-beautiful natural areas of southwestern Wisconsin. Currently, volunteers spend approximately 30 hours a week maintaining the site, according to Friends of Woodford Park member Chuck Wiegel.
