The Green Bay Packers continue to release details on plans to dress up Lambeau Field.  Earlier this year they announced an upgrade to the stadium's sound system will take place this summer.  New in-stadium speakers will be installed along with improvements around the concourses.  Updated scoreboards are planned for each end zone and at the south end of the stadium, construction will begin in 2012 on an upper deck, adding between 6000 and 8000 more seats.  The stands will rise vertically above the top row in the bowl.  Thursday, Vice-President of Administration and legal counsel Jason Weid told the board of directors the team is considering an expansion for the Hall of Fame,  currently located in the Atrium's basement.  While still in the planning stages, the Packers would move both the Packers Pro Shop and Curley's Pub to a location outside the stadium itself in the east parking lot.  The Hall would then occupy the vacated store and restaraunt, increasing square footage to approximately 35,000 feet.   Meanwhile, it's all quiet on the football front.  By this time of year, Mike McCarthy would have normally conducted his rookie orientation camp, his quarterback school and the mandatory mini-camp for veterans.  Organized team activities usually take place through the first two weeks of June.  Wide Receiver Donald Driver's annual charity softball game will still go on as planned, June 5, at Fox Cities Stadium in Appleton.
