We've been driving to nearly every game since the beginning, and traffic was dramatically worse in 2016 than it's ever been. Getting from the parking lot to South Cap or 395 took about an hour after two of the NLDS games.
The NLDS games were packed and no one left early so I can understand traffic at those games. It was the games with 15K fans and terrible traffic that drove me nuts this year.
If the Nats had made the NLCS I came to the conclusion that there was no way I would be able to attend all three home games. Getting home at 2 in the morning three weeknights in a row would have been too much.
