We are proactive and do it ahead of time. I actually have a plow for my truck (Ford) and for our International tractor. We even have one for our ATV but I don't put that one on unless absolutely necessary.
Holy smokes, 3 feet of snow. I'm glad that was not us. We too put our plows on already. I think it is better to be ready than not. My husband also plows for our neighbor (family) so it's best to be ready.
We got dumped on here too. We are supposed to get another big storm just in time for Christmas. The snow we have isn't going anywhere soon so I could care less about more in time for a White Christmas. We put our plows on early too.
