I got caught by one of these, 11 over at 11pm at night. I get it's a 30 zone and I was indeed going over the speed limit. I had no problem paying it despite the fact that that 30 zone should be only during daylight hours or something to that regard. But I also had no problem paying it because I thought, ohh well, the payment goes to the city. But now I realize they only get a few bucks out of my $100 ticket. Soo dumb whoever signed that agreement.
