conditions, and other factors that may affect safety while navigating. For
safety, always resolve any discrepancies before continuing navigation, and

• Always be mindful of the effects of the environment and the inherent
risks of the activity before embarking on off-road activities, especially the
impact that weather and weather-related trail conditions can have on the
safety of your activity. Ensure that you have the proper gear and supplies
