I’ve chased snowstorms many times over the years and have never really been stranded for more than a day, or two at the most. I generally try to position near major highways, which is certainly easier if it’s a spot near the coast or near cities and not mountainous areas. I have a decent 4x4 truck and I carry most of the implements to dig out if necessary.
if it did end up being like that famous photo of the cars buried on the interstate in NE in ‘78, I guess life would just have to wait on me to return.
