Mary Avery Keen, Mason Keen and Jess Causey had a busy day Monday. They set up a lemonade stand on the corner of Manningham and Wood Valley roads. They plan to send their profits to help with the cost of cleaning up the oil spill in the Gulf of Mexico. The trio made about $90 in sales. Not many youngsters would brave the 100-degree heat of July to help aid the environment. Good job trio!
