The last scare text I received , I responded with , "Contact my lawyers at Smith and Wesson".

I know it feels good to reply like this but I wouldn't... they don't care and aren't scared, and ANY reply just lets them verify that there's a live person at that number, getting you even more texts...
In the legit sense, I went through several "We'll send you a bill" toll boots on my extended IZ trip. Still waiting to see if Canada or New York try to track down my Texas plates...
I had a friend that did get a 75¢ bill from Canada. They went back and forth,by mail, with the stamps alone far exceeding the 75¢. He finally sent them a check for the 75¢ and their response was it was 75¢ Canadian. He eventually got it paid to their satisfaction. Don't think he's been back since.
I guess they could black ball you at the border or something like that if you don't pay. If you try to go to Canada in the near future, Trump's policies with Canada could foreseeably get you an arrest.

Or are the Canadian too nice for that?
