The band started to play as more than 900 students took their seats on the floor of the red and blue McKale Center at the UA’s 149th Commencement Ceremony on Saturday morning. Families and friends of students filled the stadium from top to bottom, cheering as their students entered to take their seats. The first hour consisted of a series of speeches by representatives from the Arizona Board of Regents, Student Affairs and others. The last half hour was full of cheers as each of the college’s graduates were recognized. Students moved their tassels from left to right, and then a snowball fight with cotton balls ensued.
