Create defense to nuisance claims re: racing facilities

HB 639 creates a legal defense for racing facilities and racetracks against nuisance lawsuits brought by property owners within a five-mile radius who purchased or built on their land after the facility was constructed. It states that claims based on typical operations - like noise, traffic, or lighting - cannot succeed if the facility is lawfully operating. The defense applies regardless of future changes to the facility’s size, technology, or racing types, but does not override environmental laws, health/safety regulations, or claims for physical damage or injury. This bill directly affects property owners in the defined area and ensures racing facilities cannot be sued for normal, lawful activities.
