The relay includes a Survivor Celebration, Caregiver Recognition, Luminaria Ceremony and entertainment.

The event takes place at George King Field at Strath Haven High School, 205 South Providence Road in Wallingford.

The activities are free and open to the public, until 11 p.m. on Friday and beginning 7 a.m. on Saturday.

For the 14th year in a row, Penncrest High School won the Delaware County Envirothon, a competition that tests students' knowledge on environmental science topics, such as wildlife, forestry, aquatics and alternative energy.

Ridley High School became the first school to send two teams to the Delaware County Mock Trial playoffs in March, said the group's adviser, Christopher Seymore.

Since October, students had prepped as both the prosecution and defense for the case that dealt with a high school student allegedly harassing and bullying another via e-mail, Internet chat rooms and Web pages.

Ridley, one of three area schools with two teams, went undefeated during the regular season. This was the fourth year that state rules allowed for more than one team to enter from the same school, Seymore said.

Ridley's White team defeated Merion Mercy Academy in the semifinals, held at the Delaware County Court of Common Pleas in Media. In the finals, the White team lost to Notre Dame Academy, which had defeated Ridley's Green team the day before.

For the White team, juniors and seniors Jim Kellett, Shane Radick, Andrew Shaner, Allie Hilferty, Yewande Alade, Victor Poiesz, and Alison Gutsche participated as attorneys or witnesses.
