Fighting City Hall
I ran into my friend a couple of days ago and he excitedly told me he had beaten the ticket. It turns out that the city had not proven that the van was in a residential neighborhood, which is a requirement of state law, and which I pointed out in my essay.
So, it turns out that you can win, and that the City of Boulder is not so all-powerful in these things. Now I guess we'll see if they move or remove the van, or if they just count on the next victim to be unaware of the law.
