As a college professor in the Republic of California, I have a lot of fun keeping the RKBA issue alive via several activities.
Yes, I "carry openly" (magazines, that is) and regularly leave back issues in the Staff Dining Room at the cafeteria. Sometimes they stay around for weeks; other times, they disappear overnight, which requires immediate replacement. Occasionally, I find a "kindred soul" who occasionally joins me at the local range. I'm trying to form the "College Rod & Gun Club", just to antagonize the liberal-socialists, but few others want to be that provocative.
I have a few pistols included in my computer screen saver in the classroom; no negative comments from students or management.
I also wear the NRA member pin in my lapel, and get no negative response; maybe it's because I'm 6' 3" and in good shape, notwithstanding my advanced age...
