Target on Mulberry Tree, Hanford Reach, Washington.
In 1990 two scientists sent jars of Mulberry Jam made from berries collected along the Hanford Reach to US Secretary of Energy James Watkins and Washington Governor Booth Gardner. The jars of jam, believed to be contaminated with radioactive Strontium 90, a byproduct of nuclear weapons production, was marked "Radioactive - Do Not Eat". The jars were accompanied by a note from the senders, Norm Buske and his wife Linda Josephson, which read ``This mulberry jam is a token of the future hazard of unidentified, uncontained and unmanaged radioactivity at Hanford,''
