|Green Bay Packers Practice Facility (1997–present)|
Ray Nitschke Field is one of the two outdoor practice facilities of the Green Bay Packers (the other is Clarke Hinkle Field). These fields, together with the Don Hutson Center, comprise the team's training complex.
On June 18, 2003, the Brown County Board voted 23–0 to approve a new lease for Ray Nitschke Field which gave the Packers the use of the site through 2020. The lease began in 2004 and started at $125,000 with an increase of $5,000 in each succeeding year. The Packers had been leasing the field from the County since 1997 for $15,000 a year. This field had an artificial FieldTurf surface, installed in 2004 (Clarke Hinkle Field has a natural grass surface).
On August 1, 2009, the Packers unveiled major renovations to the practice facility, including bleacher seating for 1500 fans, a sound system for announcements and music as well as natural grass field with underground heating. The heating system will enable the team to host outdoor practices in the winter, something they have been unable to do in the past. The exterior facade uses the same brick style as Lambeau Field and the 170 × 75-yard field is considered a state-of-the-art practice field unlike anything else in the NFL.
