Even though I am sorry about this young woman, I don't know if they are actually blood guilty. I remember years ago attending a weekend class in a community college after it snowed and I did a 360 degree skid. What a scary experience.
Now, every school I know of closes at the merest suggestion of snow or ice. They are worried about LIABILITY more than anything else. I don't know where this tragedy took place, but I believe around where I live the meeting would have been cancelled.
I also remember back in the day the talk about how you shouldn't miss meetings unless there was a good reason. I also noticed the people doing the most finger-pointing weren't in the work force and were not exhausted like somebody with a job.
But, with no announcement of the hall being closed due to inclement weather, you can rest assured some die-hard would show up!
