Parents and grandparents cried. Brothers and sisters looked on in awe. Educators stood proudly and beamed as they handed diplomas to this year's high school graduates. And the graduates, resplendent in their caps and gowns, whooped and hollered and exchanged high-fives in celebration of the milestone. The graduation ceremonies, which began in Prince George's last month and concluded Friday, capped another year for the county public school system. About 7,000 students graduated from 26 schools, including Tall Oaks Vocational High School in Bowie, Croom Vocational High in Upper Marlboro and the alternative RICA program in Southern Maryland. Most of the ceremonies took place at the Show Place Arena in Upper Marlboro and Comcast Center at the University of Maryland, and featured speeches by valedictorians and others.
