For a remarkable and singular experience, there's nothing that matches up to the Pacific Coast Dream Machines Show - Half Moon Bay's massive celebration of mechanical ingenuity, power and style known as the "Coolest Show on Earth". It's a whimsical, fascinating, amusing, curious and absolutely unique show and tell spectacle featuring 2,000 magnificent driving, flying and working machines from the 20th and 21st centuries. The world's coolest cars of every era and style, model-T fire engines, vintage busses, custom motorcycles, tricked out trucks, sleek streamliners, one-of-a-kind antique engines and tractors and historic military aircraft will be among the mesmerizing displays.

This year's 22nd annual show is expanding to two days - April 28-29 - and adding a Championship Demolition Derby (on April 28) to the lineup of awe-inspiring attractions. The show is open from 10 a.m. to 4 p.m. at Half Moon Bay Airport, located in the picturesque seaside town of Half Moon Bay about 20 miles south of San Francisco.
