So I live in a super small town, like population 200 and people really really HATE change. I'm talking you're ostracized because you don't go to church every Sunday.

Your kids are going to have a bitch of a time. I never fit in and I moved here when I was 7. My brothers had an easier time of it. I suggest enrolling your kids in whatever popular sports are going on, have a neighbor kid cut the grass or babysit the kids. You really need to immerse yourself into the community and since you're already off to a bad start it is going to be a lot more work.

What about having a big potluck or like a pig roast? Do something that shows the community you want to live here and be accepted but that this is your home. Talk to the football team and offer parking on YOUR terms. Have your kids invite people over and be the super gracious and happy hosts. In my town the hockey community latched onto my family because my dad and mom volunteered a lot.

Right now you're the city folk messing up the routine of the hometown. Shop at the local grocer, ask for local recommendations for food, shopping, services. Even if you never use them, showing that you support the community is important. You were right not to put the signs up, that would have put you in the shit house for a really long time.

Go to local meet ups or groups and try and find a niche that you like.

Get REALLY into Halloween, that may help. Do set up a "graveyard" display and hand out bitching candy. At Christmas volunteer at a church. It may seem like a lot of work but my parents did holiday stuff for a year or two and they were accepted.
