I think the quote fits a lot of us.
I think Stan and I are a bit different from whatever the average tourist is, in that we do a lot of pre-trip study. We read up on the history and art of wherever it is we're going, starting months in advance. And I'm a language junkie, so I always make sure I know something of the language. This is in addition to checking out museums and other points of interest; museum visiting is probably our main activity while in Europe.
When we travel in the States, we drive, and in the back seat of the car is a box full of reference books: geology, birds, wildflowers, animals, history.... We consult these on the road, and they make up the bulk of our evening campsite reading.
Does this make us savvier? Nope, but the preparation suits our personalities and our travel style. Our lifestyle, really. We just love learning. As our favorite Roman guide, Francesca Caruso says: "The more you know, the more you see."
Interesting topic, Allan, as usual.
