Vegetable Stock

Brother Evan sent me an email requesting my veggie stock recipe in anticipation of Aaron's arrival for the holiday.  This recipe is the result of thirteen years of experimentation as we've had vegeterian guests for Thanksgiving that many years (Amy's sister Katherine and husband Bernard). I make a seperate stuffing and gravy from this as well as some soups as our Thanksgiving runs from Wednesday through Sunday. We have turkey and since they eat seafood, lobster has to do.  I'd like to know if anyone gets acceptable results trying this, and please let me know if you come up with any improvements. I'm all ears.
