We always decorate turnips instead of pumpkins. We used to carve them when I was a child until the "Turnip Incident" which ended with my mother spending Halloween in emergency getting stitches in her hand while a neighbor took my sister and me trick or treating. Now it's garbanzo beans for eyes, paint for the features, etc.
We usually go apple picking in October & make lots of baked goods (apple streudels, baked apples, apple bread (my favorite), apple pies).
With DS, I take him only to 4 houses, neighbors I've known for years.. Much more than that would be too overwhelming for him.
My family (my parents, specifically) also celebrates Samhain as a religious holiday, but not on Nov 1 (nor its eve). My parents always separated the "secular" Halloween, May Day, etc. & allowed us kids to have that and celebrated the religious holidays at the cross quarters. So our Samhain celebration will be when the sun is at 15° Scorpio.
