Closing sidecountry gates would save lives. Why not make those who want to experience the backcountry earn their turns? That would definitely prevent a lot of uneducated young immortals from getting in over their heads. And save the Ski Patrol from expensive, painful rescues which only distract them from their main purpose, which is controlling the inbounds and keeping resort skiers safe. Undoubtedly an unpopular idea, I admit, but I always wondered which lawyers signed off on those sidecountry gates anyway. (I'm not a lawyer BTW)
I'm not a lawyer either, but I think the theory is that once you start being selective, you are responsible (or potentially responsible) for the accuracy of your assessment.
I like the fact that JH puts the current avalanche assessment (low, moderate, high, ...) according to the avalanche center near its gates. It might make sense to post the day's bulletin up too. I know it is extra work, and will be ignored by most, but it might enlighten a few who aren't even aware the centers exist. On the flip side, there is the false-sense-of-mastery argument agains it. Hard to know what is right.
(By the way, I've only been in sidecountry a few times myself, and always with an experienced local guide and a beacon.)
