Major improvements recently. I really enjoyed the Friday night game in 2017. Free football parking on campus, which is an extreme rarity. Decent sized walk but it is through campus so I sampled one building after another. Tailgating is strange because the fans don't have much of an attitude, completely unlike basketball. They mostly expect to lose. Best tailgating is near the Krzyzewskiville area, which is not far from the stadium basically behind the old basketball practice arena. Then Cameron Indoor is right there atop the hill overlooking the football stadium.
They have tours of Cameron Indoor but make it somewhat of a hassle. In contrast, the new Duke Sports Hall of Fame is attached to Cameroon Indoor and you can tour all you want. There's even a little corridor that is supposed to emulate the sound of Cameron Indoor. I had Grayson Allen walk out of a basketball tape session in that building and politely say hello to me, despite my Canes garb. Then he posed for pictures with another Canes fan wearing a Shaq Quartermann jersey. It was amazing how different he was in person than his reputation.
Football visitor side is opposite the press box. That's all I remember. Smallish stadium with only one deck so no seat is terrible.
Make sure to check out the Duke Chapel. One of the most impressive structures on any college campus.
