Food Truck Invasion in Tradition Square, Port Saint Lucie will switch to 1st and 3rd Fridays starting in September 2014. Bring a few lawn chairs and your dog if you like. Event runs from 5 – 9 p.m. and trucks take credit/debit cards. Watch the sunset over the church steeple or the lake, visit with neighbors and friends from town, enjoy a large buffet of dinner choices. It’s a local favorite, and a great way to start your weekend.
