I’m going to have to dispute that and you may wish to look at my screen name title before exaggerating further
It’s been well over a decade since PA turnpike had multiple wrecks and fatalities from a snow squall
I too travel all over PA for 30 years in the winter and have Never encountered such. Some 1X2 mile area somewhere is PA May have such a debilitating squall once or twice a year on some remote or non main Highway or area. The idea that this is frequently encountered by interstate travelers in that area with disasterous white out results is Absolutely False.
