Austin will celebrate National Night Out this weekend and early next week. This Saturday, Police Chief Art Acevedo will lead a kickoff party at the Mueller Airport Park to get things started. The event, from 10 a.m. to 2 p.m., will include live music as well as chances to talk with Austin/Travis County first responders, see the exhibitors’ booths, eat free hot dogs and relax on the shores of Mueller Lake. Then Tuesday, National Night Out moves to Austin’s neighborhoods, where there will be dozens of block parties (Austin had 480 of them last year). This will give you a chance to celebrate and meet your neighbors. Check with your neighborhood association or HOA to see if one is planned on your block. If not, it’s not too late to get one organized. Go to www.nnoaustin.org for information on planning one in your neighborhood.
