This is Cassy from Ripple Public Relations, and I wanted to spread the word about an amazing benefit coming up on Saturday, May 11th at John Barleycorn River North (149 W. Kinzie). Chicago-based non-profit organization, The Puppy Mill Project, is holding their annual benefit to honor the “Mothers in the Mills”, just in time for Mother’s Day.
