I'll add in that I did the trip from SFO to CP several times last summer (using SFO as a warmup stop on the way to CP), and it never took more than 90 minutes to get from one to the other...
Actually, SFO is ROUGHLY a halfway point in the trip from Pittsburgh to CP (slightly more than halfway, and the sidetrip from the turnpike to the park adds a little more on top of that, but it's close)
