Merchants at Snoqualmie Ridge Town Center host their second annual Halloween event, 1 to 4 p.m. Saturday, Oct. 30.

Participants should start at Halloween Headquarters, 7815 Center Boulevard across from Snoqualmie Library, to pick up their Halloween Passport and to pass through the Happy Halloween Hallway, which is appropriate for all ages.

Trick-or-treaters can visit participating businesses to receive stamps in their passport and lots of fun treats. Each person who receives stamps from at least 10 businesses will be entered into a drawing for great prizes donated by the Snoqualmie Ridge Town Center merchants. For more information, call (425) 396-3020.
