First time cooking for Thanksgiving

Thanksgiving is coming very soon. This will be my first year cooking.  Thankfully if I bomb it then we still have my in-laws to go to after and my MIL is an amazing cook. Pretty nervous about cooking but planning on doing some the night before so Thanksgiving Day itself isn't stressful and I have time to spend watching the Macy's Day Parade with Sarah.  Making the basics but is there anything that you guys have that are kinda unique to your family and is it an old tradition or a new one?
