Good for Duval. They don't need a Walmart on historical grounds. If you look at any moderately sized community there is usually a Walmart within a 5 mile radius.
Walmart always finds somewhere else to build. They have serious money.
Did you consider buying the land for yourselves and then doing as you pleased with it, or did you just bully the government to restrict someone else's property rights?
In Virginia, it's hard to travel 5 miles in any direction and not be on 'historical' ground.
But the entire state of Virginia is historical grounds. It was the central site of action in the War of Northern Aggression and the American Revolution. If people don’t want the economic development and jobs that come with the Walmart, that’s one thing, but don’t use the fact that it is somewhere near a battlefield to argue against it.
