The John Muir Amphitheatre in Martinez was turned into a driving course for kids ages 2-5 during Mini Motorland on Saturday. Youngsters were invited to drive their electric or pedal-powered cars and tricycles around a track and make pit stops, like the Walse brothers of Martinez, above. As Om, 4, stopped to fill up at the gas station, he got a little help from Neel, 9. And 4-year-old Michael Haase, of Martinez, right, was also pumping -- the pedals on his early 1970s Murray Flat Face Pedal Car -- as he climbed a hill. The car belonged to his father, Thomas, who passed it along to the next generation.
