I just thought of another idea to get Kaz's undivided attention! 💡 (but more on that later..)
I once entertained the notion of trying to find out how much it would cost to place an message on a billboard visible from the trains that lead to PD's offices. Maybe that's worth a thought? It would certainly get some attention if done right. Of course, the cost could be prohibitive. I have no idea how much billboards go for. And it would take a bit of research to figure out where exactly their office is and where workers at said office would be most likely to live. Not impossible, but a fair bit of work, to be sure.
