Forty-two vehicles filled with graduating Yorktown High School seniors lined up at Madison Center, and escorted by motorcycle police, they headed toward Glebe Road on Sunday afternoon. The cars and trucks were decorated with blue and white balloons floating through the sunroofs and some with the names of the graduates on the sides of the cars. The sidewalks were filled with neighbors clapping and hooting as loud as the seniors in the cars. The motorcade parade travelled toward Williamsburg Boulevard, turned left on Ohio and then Little Falls and then ended up at the Yorktown parking lot. More than 500 seniors graduated from Yorktown in a virtual ceremony this year.
