What is one reason why riding in cross-country ski tracks is discouraged?

Riding in cross-country ski tracks is discouraged primarily because it can ruin the ski tracks. When snowmobiles travel through these finely groomed tracks, they can disrupt the snow's texture and formation, leading to uneven surfaces that are difficult for skiers to navigate. Maintaining the integrity of these tracks is crucial for providing a safe and enjoyable experience for skiers, as they rely on the smooth, consistent pathways that the grooming process creates. Therefore, protecting these trails is essential for preserving the enjoyment and safety of those using them.
