If you live on the Westside and are looking for free outdoor entrainment, you need to check out Playa Vista’s summer “concerts in the park” series. The majority of “Playa Vistans” are young families — adding to the already hip vibe of a community that features multiple dog parks, assigned community garden plots, and outdoor grills that overlook the area’s wild marsh. Community planners are doing even more to attract a younger crowd by offering summer concerts, plays, and movie showings in Playa Vista park, where attendees are encouraged to bring picnic items and lawn chairs.
