On Sunday, several big trucks came out to honk their horns and flash their lights to celebrate a little girl named Opal who is suffering from leukemia.
When 9-year-old leukemia survivor Ashlinn Swanson told her parents that she wanted to create a stand for Casper's Lemonade Day, she also told them that she wanted to donate half of her earnings to the organization that helped their family during the worst time in their lives, the Jason's Friends Foundation.
