Tickets for the Green Bay Packers annual Family Night go on sale later this month. The August 4th event will cap off the start of training camp for the historic team’s 100th year of football. Family Night includes an 11-on-11 team practice in Lambeau Field and it is often a sellout. The tickets cost 10-dollars each. Training camp for the 2018 season will open the next morning as part of the four-day Packers Experience.
