I am very proud of my son Larry, he has been working his fingers to the bone on this, he just went down to Petaluma for a regional competition, he has to make this lift up bean bags and shoot them into a trough in a certain amount of time, he took a Gold Medal , now he gets to go to state in San Diego, if he does well here , he will go to Kansas for nationals. Very cool for a small high school like Upper Lake to have the technology like this in the classroom,wish him luck on spring break in San Diego.
