Public grinding demonstrations are suspended for the 2020 grinding season. We hope to resume our regular 2021 grinding season on Sunday, April 18, 2021. Over the 2020-21 winter, the Fairfax County Park Authority will conduct scheduled maintenance, including the installation of a new flume and wheel. Follow our progress on social media.
