Southeastern Kansas is a bit hilly and so is southern Missouri. I'm finding that once I get off the plains the state roads get a bit slower and more fatiguing to drive, especially with the winds out here the past couple of days.
With the rising gas prices, I've been a bit concerned LD's gas mileage might suffer on the Interstate but that doesn't seem to be the case. At my usual 65 mph I find I'm running just a tad over 9 mpg pretty consistently.

Teosinte and the Improbability of Maize
The ancestors of wheat, rice, millet, and barley look like their domesticated descendants; because they are both edible and highly productive, one can easily imagine how the idea of planting them for food came up. Maize can't reproduce itself, because its kernals are securely wrapped in the husk, so Indians must have developed it from some other species. But there are no wild species that resemble maize. Its closest genetic relative is a mountain grass called teosinte that looks strikingly different - for one thing, it "ears" are smaller than baby corn served in Chinese restaurants. No one eats teosinte, because it produces too little grain to be worth harvesting. In creating modern maize from this unpromising plant, Indians performed a feat so improbable that archaeologists and biologists have argued for decades over how it was achieved. Coupled with squash, beans, and avocados, maize provided Mesoamerica with a balanced diet, one arguably more nutritious than its Middle Eastern or Asian equivalent.
