So I'm walking the dog this morning, same old routine, and I pass a guy who actually smiles and nods at me and the pooch. That's nice, people usually avoid eye contact with me and Sammy. Then I notice that the guy has a hook. No, he's not carrying a hook, he has a hook instead of a hand.  So are hooks still a medical option for amputees? News to me. Sometimes, a dog walk is just a dog walk, but other times, it's a real trip.
