Remember when kids used to play outside for hours at a time, only to return home at dinnertime? As more and more kids spend most of their times in front of a screen, these days there are many who can’t relate to that. Mike Lanza hopes to change this culture. He’s authored a book, “Playborhood,” on how to make neighborhoods the best possible place for children to play and connect. He will be visiting Somerville City Hall (second floor) from 6 to 8 p.m. Tuesday, March 19, to conduct a community workshop about how to devise strategies to solve this problem. The Somerville Public Library has several of his books on display on the second floor of the Central Branch for interested parties to borrow in advance of his workshop.
