Six Sauk Valley Rotary Clubs – Dixon, Rock Falls, Sterling Noon, Rotaract of Sauk Valley Community College, Twin Cities Sunrise, and Walnut – raised slightly more than $2,600 in the seventh annual End Polio Now Walk, which began and ended Oct. 8 at Centennial Park in Rock Falls. The Gates Foundation will triple that amount in matching funds, making the total contribution about $7,800.
