The Scarsdale Public Library is bringing back “Big Truck Tuesdays.” Kids of all ages are invited to come and check out the trucks from the village’s highway, police and fire departments. Public employees will be on hand to explain what it’s like to drive the trucks and how they work. The kids are encouraged to ask questions and even climb aboard some of the machines. The highway trucks will be in the library’s parking lot at 54 Olmstead Road at 4 p.m. May 14. The police and fire trucks will be on hand at 4 p.m. May 28. For more information, call 914-722-1300.
