The 17th Annual Festivals of Speed at St. Petersburg will take place downtown in Vinoy Park. See the world's snazziest automobiles and the who's who list of cars at this annual car show including vintage and contemporary models from Porsche, Lamborghini, Ferrari, Rolls-Royce, and Aston Martin, some so frighteningly aerodynamic that the wind refuses to blow on them. This massive showcase of exotic vehicles will stretch across the grounds of Vinoy Park from 10 a.m. to 4 p.m., concluding with an awards presentation for the most impressive cars.
