Alot of park etiquette doesn't have to be taught, its common sense- ie: don't stand in the landing, don't cut people off, don't jump over the lips. I witnesses alot of problems with the ski team over on F chair,- skiing fast down into the line, kids standing on my skis, cutting in line. Alot of the adults were not much better, I heard one race team adult say to another, "I'll be right there, as soon as this "stupid guy" gets out of my way", indicating someone who was ahead of him in line. Where were these race kids taken out? Were they in the park? Just because someone has twin tips or a snowboard doesn't mean they ride park. Most of the kids who ride park very rarely venture over to F chair side, unless to ride family park, then they usually hike features.
