The San Mateo County History Museum will present An Old-Fashioned Fourth of July within its museum, the 102-year-old county courthouse in Redwood City. Children will be invited to hand-crank vanilla ice cream and then take a taste. They will also make traditional Independence Day crafts to take home with them. Museum admission will be half-price that day: $2.50 for adults, $1.50 for seniors and students and, as always, free for kids five and under.
