The Winter 4x4 Jamboree attempts to keep the trail rating current. However, weather and usage constantly alter the routes and ratings. Heavy localized rains can change a trail from a moderate trail to impassable in an afternoon. It is always wise to obtain the most up-to-date information prior to departing for a trip and be prepared. Remember, turning back is always an option!
