"What is the nature of the universe?" is simply one of the questions being explored at Fermilab. The (nearly 7,000-acre) grounds of this high energy particle physics lab include wetlands, woodlands, and the prairie seen above. Springtime brings baby bison (awwwww) and Winter, gaggles of geese — feel free to bring your pups to play on a one-acre, off-leash area complete with pond, so get those swimming lessons done early. Located in Batavia, about 45 miles west of Chicago, Fermilab includes all the Midwest ecosystems and that bison herd to symbolize its connection to the prairie and its position on the frontier of scientific discovery. The center is also a member of Chicago Wilderness, an organization dedicated to protecting and restoring natural communities of the Chicago region.
