Before their trip to the state competition, SnowBots is holding an open mini competition to showcase the robots in action - lifting, transporting, and assembling "skyscraper blocks" in 2.5-minute matches. Anyone interested in seeing FIRST Tech Challenge in action is welcome to attend the Mini Scrimmage on Dec. 7 from 1:30 to 3:30 p.m. at Houghton Middle School; enter near the cafeteria (Door No. 8).
