Want to take a free public tour of Fermilab, but can't make it out to the lab for our regular Wednesday tours at 10 a.m.? Well, you're in luck. Last year the lab piloted a Summer Sunday tour program, and it was so successful that we're bringing it back this year. Every third Sunday this summer - May 20, June 17, July 15, Aug. 19 - from 1-3 p.m., you can join a free tour and learn more about what Fermilab does. Registration is required and you will need a photo ID to enter the site.
