I have lived and traveled all over the world and everywhere I go people tell me how bad the weather is at that particular location. "Watch out for black ice," they say, or "if you don't like the weather, wait five minutes and it'll change." I'm so tired of hearing everyone complain about weather, I now refuse to comment on the weather other than to describe it... no opinions involved, see?
Western PA has four distinct seasons, but I forget their names. During one season it snows alot. In another the leaves turn colors, and in a third you'll see a bunch of new leaves growing. During the final season, lotsa stuff grows, it gets hot, it rains pretty frequently, and there is a lot of highway construction.
Use caution in Pennsylvania in the winter. Roads get icy quickly, lots of snow falls with little warning, and southerners occasionally venture out on the roads (see photo). Slow down when the weather gets bad! Four wheel drive helps maintain traction, as does weight in the back of a rear-wheel drive vehicle.
