Probably wouldn't matter in my neighborhood. I actually live in the "city" and a horse wouldn't work in this neighborhood - even a visiting one!!!! It's one street with a cul-de-sac.
In the 10 years we've been here, we've worked with many of our neighbors in cleaning it up, but we still average 6 drug busts a month and the neighborhood only consists of about 60 houses. That's a better number - it used to zero, cause no one ever called the cops, too afraid. When about 15 of us started calling, a big difference occurred. And the local drug dealers do not particularly appreciate the fact that I am home nearly all day, every day!
So now, back to your horses!!!
