I love being on the phone with someone in Washington, DC or New York or what-have-you and saying, "I have to let you go. We need to be at the barn in fifteen minutes."
While one can ride (or drive horsedrawn carts, as the oldest prefers) in the outlying areas of many cities, it's not nearly as convenient or easy as it is here, so it generally serves as a special occasion in other parts, rather than as a regular activity.
Have I mentioned that one of my favorite smells in the world is the warm, sweet scent of a horse's neck in the sunshine? And with the oldest as my front, I get to indulge my habit weekly. Ahhh.
