I'm not usually one to say I want to forego skiing because it's too cold. But this particular cold snap seems especially unusual to me in a few ways.
1) From what I can remember, most of the time if we're going well below 0 around here, it's on calm, clear nights in January after a recent snowfall. This time, these temps are accompanied by nasty winds.
2) It hasn't been cold much at all the winter so far, making it feel even colder by comparison.
3) It's going to be warming right back up very quickly.
So it makes a lot of sense to me to shut down or limit operations for a day or two when very few paying customers want to be out in it anyway, and it keeps customers and staff safer. The biggest safety issue I see, which I think was mentioned earlier in the thread, is that if there was some sort of lift trouble and and people are stuck up there in the cold and brutal wind for any length of time, it's not going to be good.
At Royal, yesterday wasn't an issue because there were never plans to be open. For today, the first change was to cancel the Trailblaisers childrens program and tack on an extra week at the end. Definitely a no brainer. Then the announcement came about delaying opening until noon today. This also makes a lot of sense, since the worst of the cold is right now and by noon it will at least be a little more reasonable to be outside. People who really want to get some runs in can do so, and staff members don't have to be out in the worst of the cold.
