Trail conditions change, and something what is hard for one driver might be easy for another, even if they are driving the same vehicle. A rainstorm might make an easy trail impassable, or a hard trail easy.
Rating trails is tough and subjective. Be aware that conditions can change and the experience level of the person doing the rating may be different from yours. While we've tried to make this system useful, take these or any rating methods with a grain of salt - use our ratings as guidelines only.
