Hours of water slides and tubing around the lazy river is always a summer day well spent. So when a free weekend popped up on the schedule, my family jumped at the chance to hop in the car with the camper in tow and head to Grand Prairie for a weekend road trip and a day playing at Epic Waters Indoor Waterpark.
