Pac-Man Level 256; the arcade game runs out of memory
Chris Dobel reports seeing a license plate from Linn County beginning with AFR. Just like that, the rollover is here.
Some counties may not have exhausted their Z stacks yet, but given an AF out there, many have them. No telling which has ZZZ or AAA.
In the future, saying the rollover occurred in October 2012 will be good enough and likely the best we’ll get. That means it took about 12 years and nine months, from 1/2/1997 to 9/30/2012, for Iowa to go completely through the alphabet, minus large blocks of letters and certain combinations that were intentionally or accidentally excluded.
