'On the Green' with the Mulcahys - Part 2

In part one of our interview series, we told you about the success that Mary Kelly and Erin Mulcahy have found in their high school and college golf careers. Next week, the Mulcahy family will be heading across the pond, and the twins will be facing a new type of challenge in an international competition. Our Casey Mulcahy has more on that with his cousins, the Mulcahy twins in part two of 'On the Green' with the Mulcahys.
