The Mercer Island Preschool Association is creating a city map of holiday lights and decorations to benefit Mercer Island Youth and Family Services (YFS), which provides services to islanders of all ages in the form of counselors, a food bank and financial assistance to families in need.

To purchase a digital map, visit www.MIHolidayLightsMap.com starting on Dec. 11. A $10 purchase includes a digital download of the driving routes, musical suggestions to create a festive holiday mood, and a scavenger hunt for the little ones. All proceeds go to YFS.
