Kids Sell Lemonade in Hopes of Treating Dad's Mysterious Brain Condition

These kids are raising money with a lemonade stand to help their dad, Virgil Garrison III. He believes something is wrong with his brain ever since he was in a car crash many years ago. But what exactly is up remains a mystery. His family is hoping a doctor at Duke University in North Carolina might be able to pinpoint the problem. It's unknown if Garrison needs any surgery, but his children hope the money they raise will help pay for a specialist who can give a formal diagnosis.
