Dogs ran free when I was a kid. They'd roam all day, coming and going as they pleased. Sure, they'd occasionally get clipped by cars- that was the price of their freedom. Humans paid an awful penalty for that canine nirvana. Dog bites were common and their feces was everywhere. Things are much better now. As I angrily kicked a couple piles of poop off my lawn yesterday I recalled the time when every home required a special tool to deal with the constant mess. Even though I can't help but laugh at the sight of good citizens walking with a leash in one hand and a bag of waste in the other, I'm pleased to live in this enlightened era.
