It’s the oldest rivalry in the N-F-L, so it shouldn’t be a surprise that demand for tickets for the season opener at Lambeau Field between the Bears and Packers are bringing a big price. One website, vividseats.com, says the average price for a ticket to that Sunday Night game is 321-dollars. That’s the 10th-most expensive average ticket for any N-F-L game in the upcoming season so far. The first game between the Packers and Bears was played 97 years ago. Chicago won that one 20-0. The two have played 196 times since, with the Packers winning 96, the Bears 94 and six games ending in ties.
