To answer your first question it is a violation to post fliers on city property. I havent heard of anyone accually get one.i myself have put up thousands of fliers up over the years with out getting one but have been warned a couple times by shop owners and such. Dont let it stop you ! Flier the city. In this day age of the internet i think its fallen to the way side but think it still has an important place in promotion but maybe im just oldschool. I will say that certain areas in the city are pretty quick about taking them down (ie: most of elmwood). Good luck and get them up!!
