Maybe I'm nuts, but I associate the smell of horse shit with romantic feelings. I have even worked in stables briefly, as a boy in the Scouts, and at the Ren Faire, where I was a squire. To me horse shit smells like: Mackinac Island in the rain, hay rides (see the salute to autumn thread), state fairs, and, of course, horseback riding.
Am I a crazy ass city boy? I also like the smell of horses
