Northfield High School will sell a four-piece set of the old gym floor at a silent auction during the 2012 homecoming game.

The recently replaced section spells the word “Raiders” when the 4-by-4 foot pieces are aligned. Bidding will begin at 6:30 p.m. on Oct. 5 at Memorial Field and will close when the second half of the football game begins. The sale will benefit the high school athletics program.

Visitors can view the memorabilia on display at the main entrance of the stadium before and during the game. The auction table will be located near the entrance, on the home side of the field.
