Thanksgiving - Food, Family, Alcohol...all the good stuff and none of the work, stress, and $$$ that Christmas has.
Memorial Day - Agree with Auggie...start of summer.
New Year's Day - CFB & Food Fest.
July 4 - If it falls on a 3-day weekend.
Halloween - Grown-up fire pit with beer/food in the cul-de-sac.
New Years Eve and Christmas are at the bottom of my list.
