IS FARM AID BEING IRRESPONSIBLE ???

Is Farm Aid being irresponsible by offering HOMEGROWN concessions—all that good tasting, family-farm identified, local and organic food - and not giving consumers a good way to burn off a few calories?

Since overweight and obesity in America have reached epidemic proportions, shouldn't something be done to help The Weight (of the Nation, in consultation with the Division of Adolescent and School Health; the Division of Adult and Community Health; the Association of State and Territorial Public Health Nutrition Directors (ASTPHND); the Directors of Health Promotion and Education (DHPE); and the National Association of Chronic Disease Directors (NACDD)) ?

Farm Aid’s HOMEGROWN Village showcases hands-on activities that give concertgoers a chance to meet farmers, get their hands dirty, and learn how family farmers are enriching our soil, protecting our water, and connecting us to our roots ... but they can't add an attraction that would promote healthy physical activity due to "liability concerns"?

According to the CDC, "policy and environmental change initiatives that make healthy choices in nutrition and physical activity available, affordable, and easy will likely prove most effective in combating obesity."

Is the time ripe for a Farm Aid (Homegrown Village) policy change?
