Children in Wisconsin could legally operate lemonade stands under a bill up for passage in the state Senate. But they’d have to hold the egg salad. The measure up for approval today would permit anyone under 18 to operate lemonade stands on private property without a permit and without fear of getting in trouble as has happened in some states. They couldn’t sell more than $2,000 of lemonade a year, or 8,000 cups at 25-cents a pop. The young entrepreneurs would also be barred from selling any potentially hazardous food, like raw meat and egg salad. The measure has bipartisan support. It also would need to pass the Assembly and be signed by Governor Tony Evers before becoming law.
