It drains the blood from the victim without biting the vein. A green tractor under mercury becomes a purple tan, yellow is turned white, red is brown, people with freckles resemble Martians or some other extraterrestrials. Sodium vapor lights are said to correct this, they are the bile-yellow ones. Maybe green tractors are once again green but at the price of ghastly yellow spread over every visible thing. I do not mind so much that modern cities are afraid of darkness.
Fear is, after all, an urban propensity.
They must light the city the same as they illumine the prison yard, or else criminal behavior would seep from every manhole and crevice. Illumination is what keeps people tame short of outfitting squad cars with machine guns. I know, I'm hopelessly biased. I truly think the farm scene compares with the best the Rockies have to offer and it doesn't cost anything to get there. I have a recipe for a healthier, prettier farm country.
