Normally, all is quiet at Wrigley Field once the Chicago Cubs' regular season ends, but it's been a noisy offseason as crews renovate the ballpark's bleachers. Officials say construction is on schedule and the bleachers will be ready by Opening Day, April 7, 2006, when the Cubs play host to the St. Louis Cardinals. MLB.com was given a sneak peak at the renovation work on Nov. 10. Most of the bleacher seats are gone, and new concrete foundations are being poured for the new seating. The Cubs are adding 1,800 seats to the outfield bleachers and the seating area will extend from foul pole to foul pole. The family section and group section that were in the corners of left and right field will be relocated, and the new sites for both will be announced before individual tickets go on sale Feb. 24.
