Argonne is an easy place to visit—stop at the reception center, show a photo id, get a visitor badge and a map but the security people do need to know that you are coming, at least 10 days in advance if at all possible. If you plan to join us at Argonne, please send mail to Nancy Rezek ( email@example.com, +1 630-252-2574) with your name, institutional affiliation, and citizenship. If you are not a U.S. citizen, she will ask you for some additional information. See http://www.anl.gov/directions-and-visitor-information.
