"The Show MUST GO ON" vs Safety of humans and critters

Sometimes I think that I am from a different planet because of the way I look at things. When any coursing or racing event is approaching and the weather leading up to the event has made the grounds questionable, conditions for traveling to the grounds less than safe, or conditions forecast for day of trial unsafe for humans, when do you cross the line of running the trial vs cancelling the trial and how soon do you do this. This is an amazing balancing act to accomplish. Perhaps the thought is; the show must go on no matter what because of the parent club, besides this is (any location) and the conditions right here at the coursing site may be different than 10 miles away. If you show up the hounds will run, if you don't, well we were here because we are tough. I can see this way of thinking as a lot of planning and effort goes into putting on an event and we are (any named club). After all, is it not up to the individual, who needs to make the decision of playing or not.
Decisions:
The field has been frozen solid for 4 or more days, the temps are not going to get anywhere near or above freezing for another 4 days with nights going into single digits. The field is frozen solid with a light covering of snow and ice. OK fast, powerful dogs (sighthounds) are at higher risk for toe injuries and stretched/pulled/torn muscles because of these conditions(?). 
Because of temps not expected to get above 25 (F) and the winds forecast to be 15 mph or greater, the humans will be at risk of asthma attacks, frostbite and hypothermia, but they are all smart and will dress for the weather (?). 
The roads are clear but a snow/ice pack still covers most rural area roads, leaving the roads less than safe. Anyone traveling to the site knows how to drive in the winter (?). 
So you are the Field Chairman - what would you do?
This is not written as a criticism to anyone or to any club. I am trying to gather opinions and insight. Perhaps my understanding of the duties/responsibilities of a FC is different than other's or perhaps my definition of safety is misguided. I am interested in your input.
