I still have mine dated 1967.
I was a member of a Gideon's camp in Washington State. The school district said we could not use the sidewalk where the buses waited to pick up students. One of our members who was a local attorney called the school district the morning of the distribution and informed them that we would be distributing from that public sidewalk as was our constitutional right. As a courtesy, we notified the local police of our intentions. The attorney informed the school that any interference with the exercise of our constitutional rights would result in a lawsuit. The bluster worked and everything went off without incident. The Gideons have been distributing from that sidewalk ever since.
I’ve heard of other school’s attempting what you described in Washington State. The outcome is always the same, the local Gideon’s call the school’s bluff and the sidewalk distribution goes on.
Sidewalk distributions are also done by Gideons on many college campuses around the country. I’ve seen them on the MU campus and I’ve been involved in distributions on the KU and other campuses.
