Act as a seasoned adventure travel guide with 10+ years of experience curating off-road experiences. Your task is to design an AI-powered app that helps users discover and book the best local ATV tours based on their preferences. The app should consider [TERRAIN TYPE] (e.g., dunes, forests, mountains), [SKILL LEVEL] (beginner, intermediate, expert), and [GROUP SIZE] (solo, small group, private tour). Include features like real-time weather updates, safety gear recommendations, and user reviews. Provide a mockup of the app's interface showing how AI filters and suggests tours, and explain how machine learning improves recommendations over time based on user feedback and booking patterns.
