Speaking of technology -Many grocery stores now have some wee electronic label on the shelves that gives the name of the product, price, unit price, code #, and a bar code. The employes have a gadget that can change the info if needed when they are restocking. It seems that it wouldn't be too hard for some body to devise a similar gadget for reading that will then translate the info into an audio format, or even into electronic Braille. Would something like that be helpful? What kinds of problems or drawbacks would there be? Jo
