UNIVERSITY CITY — Walkers participating in the Susan G. Komen 3-Day Walk for the Cure will be able to attend a 3-Day expo to prepare their 60-mile journey. Walkers will learn how to pack the perfect gear bag from coaches who will be on hand to share tips. Bags are not allowed to weigh more than 35 pounds.
