It was in a sports arena that was also capable of seating more than 2500 people, both of which are PFZs in MI. Printing fairly badly through just a t-shirt - with a gun company's name on it no less. I guess this person could have been a police officer but that wasn't the impression I got at the time.
Curious if anyone else has encountered this and what your thoughts were. Also, any updates on the legislation to remove MI PFZs?
