Fall might be on the horizon, but there’s still plenty of late summer fun to be had around the Emerald City. On our weekend radar: a popular harvest fair, a festival with tons of games, a new event for climbing buffs, a three-day extravaganza, a rockin’ bash in Issaquah and a triathlon for pint-sized athletes. Also on tap: the annual Washington State Fair kicks off on Friday with free admission from 9 a.m. to noon (with a non-perishable food donation) and the Live Aloha Hawaiian Cultural Festival returns on Sunday with live entertainment, Hawaiian crafts and local Hawaiian food.

Kids, get ready to ROCK! Kindiependent Kids Rock Concert Series returns for it's FIFTH SEASON at Mount Baker Community Clubhouse!!
