“Although we’re disappointed that we can’t all come together in-person for the seventh annual ChesLen Chase, we’re excited about the options we’re able to offer virtually,” said Oliver Bass, president of Natural Lands. “During these long months of the COVID-19 pandemic, our nature preserves never closed. It was important to us that these beautiful properties be a resource for the community. So many people have been flocking outdoors… we hope they’ll register for ChesLen Chase and give a little back to nature.”
