Want to do something that helps the planet, is delicious, and benefits Marshall County Conservation for Earth Day?  Again this year, we will offer a free ice cream cone gift certificate to every participant that helps us clean up the county conservation parks! So grab some family and friends, head out to one of the 33 Marshall County Conservation Parks and collect as much garbage as you can. Before you leave the park, take a picture of your group with the trash bags by the park sign. Then bring the trash and your picture to the Grimes Farm Conservation Center Monday, April 24 through Friday, April 28, 8:30 a.m. - 4:00 p.m. to receive your gift certificate.
