With Mount Si High School graduation around the corner, seniors are encouraged to purchase their Grad Night tickets before the bus leaves without them.

When the Friday, June 11, commencement ceremony ends, graduates will board buses and leave the school parking lot for a night of fun. For safety reasons, seniors do not find out where they will be taken until the night of the event.

About 180 students have signed up, with room for more.

Grad Night co-chairwomen Valerie Loveridge and Susan Sellers are seeking more parent volunteers to help out during the event.

They need chaperones to load buses, organize liability papers and accompany the graduates on the excursion.

For information on volunteering or Grad Night tickets, call the Mount Si main office at (425) 831-8100.
