Made in North Carolina

I have been looking around as I shop here in Chapel Hill, NC, and I remain very surprised to find so little that is clearly labeled (so you can see it without sending out a label search party) as having been made here in North Carolina. The time seems to have come when people might value such products over others, for many reasons, and retailers ought to work harder with their suppliers to make sure customers know which products are those from North Carolina.

Our local Farmers' Market has a rule that everything sold there must be grown or produced within a fixed number of miles of the market. Why couldn't retailers establish simple labels or sections - as they now increasingly do with organic - to call attention to that which is local in the store?
