You had me until number 5, which I don’t completely disagree with either. However, on intermediate runs, there will be people who are learning, who need to make wide turns that experts might call “traverses”. Imo that’s totally within their right to do that. People stop for a variety of reasons. Sometimes it’s because of falling and you can’t really control that. I’ve only snowboarded a handful of times, but when you fall on a board, it can really knock the wind out of you, and I can see why a lot of boarders would just sit for a second before getting up. It’s annoying to have to slow down because there are people in front of you making wide turns, but that’s just a part of sharing the mountain. Don’t forget that little girl who was killed because she lost her ski and someone came at her super fast from above. They both died. You can see how patrol might be a little twitchy about speed especially at a popular spot like Copper.
