July 2, 1957br/Newbergmdash;-Sidewalk hotrod was contrived by chaining their ldquo;little red wagonrdquo; to poprsquo;s garden tractor, when the William's youngsters, Daryl, 8, and Margaret Rose, 10, got down to the business of whiling away the long summer days, A pair of baby buggy wheels were added for stability. With a couple of folding chairs in the wagon ldquo;just for luxuryrdquo; they go whizzing down the block at about half the speed they could walk. Other children overtake them and pay a penny a ride. Thus far, pop, who is Dean Kenneth Williams of George Fox college, has footed the gas bill, which reached the four-gallon mark this week. He says the youngsters developed such a proprietary interest in the tractor they also do most of the garden cultivating.
