Lake Shelbyville - You can earn $75.00 for approximately two hours of your time participating in a focus group session if you are an adult male boater between the ages of 20 and 60, who is available on the afternoon of April 28, 2018. The Corps of Engineers Natural Resources Education Foundation, doing business as The Corps Foundation, is working in cooperation with the U.S. Army Corps of Engineers to conduct a focus group session with men who don’t always wear a life jacket while boating and swimming. We are seeking feedback on our “Life Jackets Worn…Nobody Mourns” campaign products, including a new mobile game app.
