About 400 children and adults attended the annual Fermilab Family Outdoor Fair on Sunday, June 14, to visit bison, sweep for insects and study bird bones.
The fairly sunny and warm weather also allowed attendees to view the sun through telescopes with the help of Naperville Astronomical Association volunteers.
The event was a success. One mother commented, “I changed my work day so I could attend the fair with my son. I wouldn’t miss it.”
