Siblings Johnny Hazzard, 6, and Ada, 5, of Winnebago, served up lemonade from the front lawn of their mom’s Oregon ReMax office on Saturday. Lemonade Day is a nation-wide program. The Sauk Valley stands, which popped up in Oregon, Dixon, Sterling, Rock Falls and Morrison, were presented by Local Explorer. The Local Explorer app provided a map of all the local stands and featured a contest to vote for the stand with the “best tasting” lemonade and “best looking lemonade stand.”
