Is the series over?

I watched season one and two completely. It is great show about how, after such a horrible tragedy, a town's residents can come together to plan and rebuild their community. I am glad they received support and donations, and now I am waiting to see what happens next. Does anyone know if the show is coming back for season 3?

Also, I am dismayed that this show/forum doesn't have more chatter. Isn't this an important enough subject to justify your time? It's sad when superficial shows receive so much attention, and things of true value fall by the wayside. Welcome to your future.
