I had a similar situation last week. We drove to Atlanta to see spend Thanksgiving with my inlaws. My wife has progressed from the "eye roll" whenever I carried to reminding me the other day not forget my gun when I went out.
My father-in-law is from Brooklyn, not sure what his stance on guns is (he doesn't own any) and can be pretty closed-minded on certain subjects but my wife warned me not to talk about guns, don't let him know I have a CHL and especially don't let him know I'm carrying. I carried whenever we went out and also some around the house and he was none the wiser for the five days we were there. Concealed is concealed and it's better to let sleeping dogs lie.
Had no problems carrying in Georgia or when travelling through Alabama, Mississippi or Louisiana.
