Please join the “GIST Clean-UP” team for this year’s Big Sioux River Greenway Clean-Up! This is the largest clean-up event in Sioux Falls and we need your help! Our team will focus on Beadle Greenway Park. Please meet at the Beadle Greenway Shelter (421 S. 8th Avenue). As a thank you, all GIST Clean-UP volunteers will receive a complimentary wine flight card to redeem at the shop at their convenience. You must REGISTER HERE in advance. Thank you!
