While I don't think you should neglect family and friends today as you celebrate, you should take time to write when you can. Perhaps after you eat while everyone's watching football, you can sneak a pad of paper under your foam finger to scribble a few words before dessert.
Many of you have tomorrow off, as well. What better way is there to start a long weekend than by boosting your word count?
Enjoy your holiday weekend, enjoy your scribbling, and good luck!
