[FAMILY] Your first birthday is a big deal. Then there’s your “Sweet Sixteen,” the year you can finally vote (18), the year you can legally booze up (21), the year you have to swallow the teen angst of your 20s (and turn 30), the indefinable year you suddenly become “middle-aged” (31) and the year some cheeky cashier asks if you want “the Senior Discount” (?!). So when the historic Banyan Tree of Lahaina marks its 132nd year of existence, it’s reasonable cause for a weekend celebration. The Saturday party will feature contemporary Hawaiian music and dance with Wilmont K,EBituing Silangan Filipino Dance Company, Kawika Lum Ho and Kahala Moon. Sunday’s festivities include more live music with Kalani Smythe, the Watanabe Taiko Drummers and traditional Japanese folk dancing,EBlacksheep Belly Dance and BellyRoll Dance Companies,Eas well as the Internacionales Pasteles.
