The average American who travels outside their home county for Thanksgiving departs at 3:40pm today and travels 300 miles before arriving at their destination at 9:40pm, where they’ll stay for almost three days. Every $10,000 increase in county median income boosts distance traveled on Thanksgiving by 35 miles. My secret to not gaining weight; eat slowly, go easy on the appetizers, drink lots of water, and wear tight-fitting clothes.
