A tribute to a great life

I have this friend who’s mother just passed away. She was a school teacher for over 45 years in the same school district. She has become a hero for so many lives, and now that she has passed my friend wants to honor his mother in such a way that she will always be remembered. I had the idea of having one of those memorial plaques made in her memory. Not something small, but something really large that everyone for all time will be able to see. I think we should have one placed in each school that she has taught so her memory will live on.
