Have you gone to the office of the president of the university and asked to be able to carry on campus? Until you have you can't actually say that you can't carry on campus. I may not agree with all of the provisions of the SDA, but for now that is what we have. I have worked for a university for over seven years. I know the secretaries in the presidents office and from time to time I stop by and ask if anyone as been in and asked for a letter from the president. In those seven years no one has been in and asked. I know that you may not like the rules as they are written, but until we get Article 2, Section 26 of the Oklahoma Constitution changed we will be limited by the state on where and when we can carry.
I didn't know that this was an option until recently so no I have not. However, I am actually in the process of writing a letter that I can hand deliver to the College President that documents my qualifications and experiences and explains why I expect to be allowed to carry on campus. Although I am preparing to do this I do believe that it should not be required. I would like to thank you all for the comments so far. This really helps but please do not get in to the usual in-fighting that is common on forums. As my father said "stand together or fall alone"
