I think of horses as things on ranches. Or in stables. I mean, one time I saw a man riding a horse down the street in the City of Industry in Southern California, but that was just one time. The man looked like he had recently immigrated from rural Mexico, so he was just getting around the way he was used to getting around. But no one else in the City of Industry does that; everyone's in their cars.
In my workplace here in the Washington, D.C. area, one woman has four horses, like in her backyard. She lives in rural Virginia; every morning, her eleven year old daughter exercises two of their own horses, and two others.
Like Mary and Joseph on the way to Bethlehem, they stop and get water at strangers' doors, get back on their horses, and go about their merry way.
Having grown up in SoCal sprawl, my immediate reaction is to wonder 'What is that?' But on second thought, I guess it's, well, community.
