The first recorded mugging in more than 9 years (according to the State Police) in my town happened last night just 2 blocks from where I live, on a sidewalk where I often walk my dog. It was an elderly man (about 75 yrs) walking his (small) dog at 11pm. Guy walked passed him, turned around and clubbed him over the head, kicked him, and took his wallet. I thought I got away from this crap when I left the city. I'm going to take some late night strolls in the near future, trying my best to look like a defenseless old man. Possibly "clean up the streets" a little, eh?
I would leave your dog at home, I don't think anyone will try if you are walking him. Try renting a Chihuahua for a stroll and go singing "I'm in the money, I'm in the money!" while limping.
