EAST GREENWICH —The Our Lady of Mercy School parking lot was transformed into a giant costume party on Friday, Oct. 25. Thanks to the efforts of the OLM Parent Teacher Group’s Socials Committee, students and families, all in creative costumes, were treated to a festive night complete with a DJ, food from Haven Brothers Food Truck, games and prizes. Families in attendance decorated their trunks and parked in a large rectangle, keeping kids safe while enjoying treats from all.
