It's 15 miles for me. Which is close enough; for now.
The issue I see in this "report" and the busy-body's concern, is that they're expecting the Feds to "do something" about it. Sure! We can all put in the work right now to grow our own & preserve it. But what about when we're 80? or 90, as the case may be. Still gotta eat right? What if prices go out of the reach of fixed incomes?
I'm looking at this from the rural community point of view. IF our local chain goes belly up, and the independent stores (only 2 of those within the same relative distance) we also have a couple butcher shops, farmer's markets, farm stands, etc. You still see signs along the ends of driveways listing eggs @ so much a dozen. The local communities need to plan out a way to feed people or make it affordable to feed themselves.
I've been following the thread (elsewhere) where I first saw this. People are saying local milk deliveries and other trucks are starting to make the rounds again, out in the boonies. People are mentioning co-ops too. And that's all well & good if kids stay on the farm or at least in the area to carry on. Some ARE starting to abandon the cities and come back; homesteading is a popular daydream for some city people.
CSAs and co-ops are big here too. So I'm pretty sure a local market would develop and expand. Still - takes an idea, a plan and leadership.
Secondary impacts from losing affordable grocery stores locally include losing other businesses as well. Perhaps realizing that, our Tractor Supply has been sponsoring/hosting a farmer's market.
