Continuing westbound on Interstate 80 through northern Illinois, we crossed over the Mississippi River into Iowa at dusk. We counted on driving well into the night in order to make Nebraska fairly early the next day. The "World's Largest Truck Stop" drew us off the highway for a quick bite to eat, but there was a Truckers Jamboree going on, giving us a chance to see a large number of Iowans and find out whether they live up to their giant corn-fed stereotypes...The tallgrass prairie is an ecosystem native to central North America, with fire as its primary periodic disturbance. In the past, tallgrass prairies covered a large portion of the American Midwest, just east of the Great Plains, and portions of the Canadian Prairies. They flourished in areas with rich loess soils and moderate rainfall of around 30 to 35 inches (760 to 890 mm) per year.

One of the last large untouched patches of prairie left in Illinois is preserved as a state park about 50 miles southwest of Chicago. Goose Lake Prairie State Natural Area contains a patchwork of old-growth tallgrass prairie (it was always too poorly drained to be useful to farmers or other development). As a result it's a refuge for rare prairie plants, moths, butterflies and other insects, and a great place for birding.
