None of NE City's ordinances are online. Last year after I got my permit, I called the city office just to double check if they had any local laws against concealed carry before I traveled there. That is how I learned about their ordinance. The clerk mailed me a copy of it, if I still have it I will scan it and post it here for you.
I would love to make another run at getting it changed, but it is going to take a lot of local support. When I spoke before the board there last year, except for a brief statement by one resident, it pretty much seemed like it was me against the world there. The police chief was EXTREMELY vocal about his thoughts, and the people in attendance, including all but one single board member, seemed to side with him.
