Except that many parts of the Arsenal are off limits to humans due to the fact that they have, in fact, not been able to clean it all up. Yes, it's great that huge pieces of the land are open to tourists, but the fact that so much of this land, which was farmland until the U.S. condemned it and told the inhabitants, many of whom had ancestors who homesteaded this land back before the Civil War, to clear out so they could manufacture munitions, is a sad tale not told so often. But the toxicity of the soil doesn't come from what happened during WWII, but rather because the U.S. government loaned the site to businesses who manufactured poisons which further killed the soil. Make no mistake, I am very glad that this area has become a wildlife refuge and is free from greedy developers, but so many are unaware of exactly why humans are no longer allowed to inhabit this wonderful place on the prairie. I drive through the Arsenal, occasionally, and even though the farm houses are gone, I try to pick out the trees of those who planted them, many, many years ago.
