Skied Aspen this morning. The good news was there was at least 5cm of fresh snow on the trails as of 930am. The unfortunate thing was of the 3 other people I saw on the trail, all of them were breaking Park rules on ski trails. 2 people were skiing with off-leash dogs, while the other was dog sledding, weaving in and out of what remained of the tracks. I informed these individuals that their use was inappropriate. Still frustrated at the end of my ski, I decided the most productive thing was to report the incidents to the Park Patrol.
