GPS

They can implant pets with ID tags in case they get lost. They need to do the same with people, or at least me. Last week I went for a walk and learned that not all the streets in this area run parallel to each other. Well, at least not for the entire distance of the road. I also learned that different roads have the same road name. Needless to say what started out as a quick 1/2 hr walk ended up being a 2+ hr excursion. But at least I learned expanded my knowledge of the local and not so local area. But all's well that ends well and I eventually made it back home. Thank goodness for cell phones and knowledgeable housemates. :)
