Yep,
A municipal ordinance can be made up over night if the wrong folks spot you.
I have done a couple of elementary school presentations, and even getting the nod from the teachers and principal, I was hesitant about it.
In the end it all worked out but there is now a group of people who know what I have in my home and I'm not always eager to let others know about my hobby if I don't know them.
That's a bit off topic, and I think a photo with your pet is probably quite acceptable.
