Today I read the phrase "if the u.s. were invaded there would be a gun behind every blade of grass" and it got me wondering. Would there? Cue autism. According to joogle, "since there are 6,272,640 square inches in an acre: times 50 blades per square inch equals 313,632,000 blades of grass on average in a well kept acre of lawn grass. Very fine grass will have well over 600 million blades per acre, coarse forage grasses as few as 10 million or less blades per acre." Going with forage grass, thats 10 millions per acre. 3,856,506‬ acres of official grassland in the u.s. 2.3 billion acres of land in the u.s. Thats 38,565,060,000,000 (38.56 trillion) blades of grass. If we're being *extremely* conservative, the lower bound, factoring in all other types of land, golf courses to national forests, lawns to shrub land, it's probably in the 75 trillion blades of grass range, minimum. So the better question is not 'how many guns are behind every blade of grass', but 'how many blades of grass for every gun?' There are 393 million guns in the u.s. Thats 1 gun for every 190,839.69 blades of grass, divided by 10 million (thats blades per acre of grass) = ‭0.019 guns behind every blade of grass, a 1.9 percent probability per acre. It's the u.s. we're talking about, lets call it an even 2% chance. So now we know. People, we have to get those numbers up. We don't even live up to our reputation!
