You will always have a small percentage (larger if the game is a goner) leaving because even if your residence is close by you could be stuck in traffic for literally hours-and today is a workday. Those people that your tv saw leaving in their cars were likely not "hard core" and believe-as I did sitting at home-that based on the two prior games there was no chance coming from a three run lead in the last two innings. Keep in mind the Dodgers have an enormous Latino fan base. They didn't leave until after the game was well over.
Hopefully, Belli's HR-much like Gibson's HR-will push the Dodgers forward to win the Championship series and onto the WS.
