Be prepared on December 24th to have your supplies ready to line your walkway with luminaria. Candles are placed in a bag with sand or birdseed in the bottom. Light your candles and for 10 hours and the streets of Grandview Heights and Marble Cliff will shine! The brighter the streets on December 24 - the more scholarships! In the event of inclement weather on December 24, residents are asked to line the streets on December 31.
