Doug,
My condolences to you and your family at this time..Sounds like she was quite A woman,and someone whom God shed abundant wisdom upon to have even been as determined and accomplished with the few things you mentioned she did with the tree and the woman you married..
Now all the GOOD SEEDS she sowed into you and your family are yours to remember her by,her "words of wisdom" so to speak,and as she has spread them to you,you in turn as well,shall spread them even further abroad to others in this world.They are treasures to you and yours,so keep them close,and water them into others lives with Love,as your Mother did.And she shall be alive in you through those seeds and whats really cool,is that wisdom she gave along time ago which you may of forgotten,will come roaring back to you as if yesterday,and she will still be close to you in those thoughts..
God Bless you Doug,and your family.
Kevin
