Shout-out to emma.chenier for the sad but true caption. Why can't summer last forever? On that note, Nighttime Zoo: Koalafornia Dreamin' ends on Labor Day (Sep 1) so you have just about a week to come enjoy the festivities and tag your Instagram photos & videos with #NighttimeZoo for a chance to win a behind the scenes tour for four of the sdzsafaripark's new #TigerTrail.
