Don't criticize anyone's gearing choices until you've ridden 100 miles in her terrain. 
Back in my racing days I could get up any given hill in my 42x21, but even then, an Appalachian metric century full of them would leave me crying. 25 years later there's zero chance of my old lady legs pushing those gears, and I'm not a bit ashamed of it. Putting on a cassette with a 27T sprocket was the difference between having fun on Columbus Fall Challenge vs the tough steep training centuries leading up to it that I did with a 30x25.
Western PA is steeper than Ohio, even. Let the gal have her low gears already.
