Earlier this summer, we spent the day at Fermilab National Laboratory with some friends enjoying their annual “Family Outdoor Fair.” It was good fun. We scooped for pond life, netted for prairie insects, took and examined soil samples, observed an amazing menagerie of raptors, tested a falconer’s tracking device, saw a collection of fossils, tried our running speed against that of an American buffalo, observed an actual herd of bison, and a lot more. All in all, not bad for a few hours on a Sunday afternoon. Check out the photos.
