Sigh - you have no idea what you're talking about which is why I asked you to good things. Regardless of how you feel about the name, the challenges faced by people living in food deserts are real.
Poor people in remote, rural communities have similar health issues and challenges people in urban underserved places do. I'm sure you have some anecdotal evidence of people driving 30 miles into the next country or city to go to the grocery, but the fact of the matter is that isn't a regularly occurring event. Between my current job, my previous job and a board position, this is something I deal with pretty regularly. There are plenty of small town people in the middle of nowhere who have just as much difficulty getting access to medical care and healthy food as there are in food deserts.
