Hey that would be a wonderful opportunity to be in the planning and design team of the ATP tournament at Cincy this summer.
I have attended the tournament for many years and know that it is exceptionally well run. They are seeking volunteers for every area imaginable.
I would recommend if you are wanting to be an intern in the guts of the design team that you
1. study what they do, organizational and management structures, and operations, and have the ability to articulate to them where it is that they excel.
2. Maximize any connections with some of the key people or seek to build relationships with them.
3. Begin to imagine how you might meet a specific need that they either know about or that your research is able to discover and communicate your willingness to be part of a team that can help solve that issue.
Hope that helps.
