E-mail from a Jersey-Big Apple commuter:

I live in Randolph, Morris County. Always get to my polling place right at 6:00. Always the only one there. There were 15 cars in the lot when I got there.
When I got to my parking lot to get to NYC for work, the lot had 50% more cars than normal. My gut is that folks getting in early to get home in time to vote this evening.
