The Sandbar family created a contest and put in their guesses as to when baby will arrive. Each person picked a date and time, and for the tiebreaker, baby's length in inches. The entry closest to the actual time without going over wins.
If this baby is 49 inches, as Andrew guessed, we might have some problems.
Next time you're in the bar, be sure to congratulate Dave. He's pretty excited about baby's arrival. And be sure to tip well, diapers are expensive!
