As you all know, my DD is getting married in July 2018. Her future in-laws have invited us to spend Thanksgiving with them. I have no idea how formal or informal they are, but I suspect casual by the fact that they own animals (including llamas) and my future son-in-law always dresses casually.

Question: What should I wear (I dislike dressing down, so this is going to be challenging) and what food should I take? I'm thinking about making Pumpkin Cornbread.
