Bring the family for an evening concert in the Grass River wetlands. Frog calls are as distinctive as bird songs. Our naturalist will be your guide for listening to our amphibian friends as they tune up their voices for a froggy chorus. (Participation in the introductory frog class on March 22nd is a bonus, but not required.)
$5, please register in advance at www.grassriver.org. or call 231.533.8314.
