And this is what bothers me about the special plates that many places issue. There should be a unifying theme to them so that it's easy to tell the state/province that it belongs to. I really like that Ontario places a logo on the left side for special plates, with the rest of the plate looking like the standard issue. It makes it easy to tell it's an Ontario plate from a distance.
Heh, you'd hate Oklahoma. Not only do we have the state plates and all of its special plates, but every First Nations tribe in the state is also allowed to issue license plates. The bigger tribes just contract it out to the state, which gives them a number pool that doesn't conflict with the main state issue (Chickasaw Nation is CN##### for instance) and the plate at least uses the same font as the Oklahoma plate, so it just looks like an Oklahoma special plate. But some tribes handle their own issue. These tribes have their own number pool and plate design, and handle the issuing and fee collection through their tribal government. Some of them even still use embossed plates.
I kind of wonder how many traffic cameras actually recognize some of the more obscure ones, like the
the Otoe-Missouria tribal plate (every man, woman, and child in the tribe could have three cars and they'd still have a few plate numbers left over in their 4-numerical-digit scheme for anyone who isn't a man, woman, or child). I have access to Chickasaw and Choctaw-plated vehicles, and those are recognized by OTA just fine, of course, but I'm not sure if that's true in states further afield from Oklahoma, as I've never had the opportunity to test it.

I like the slogan.

Since we've done the "Oklahoma is OK" thing before, though, maybe it should just be "Oklahoma: It's not Texas." Leave it to the reader to decide whether that is a good or bad thing.
