As I noted in my post last month, as of Oct 31 I had not seen Hawaii or Mississippi since I started this in October 2007. On Dec 1, I saw Mississippi, and on Dec 2 I saw Hawaii. So I've now seen all the U.S. states since I started this in October 2007. Thus I'm switching to a new format, keeping track of when the last time I saw the plates I haven't seen in the month I'm reporting on. So the following plates did not appear in the list above but have been in my lists since Oct 2007, and I've categorized them by when they last appeared.
Not seen since October 2008: Arkansas, Oklahoma, Oregon, South Dakota, West Virginia, U.S. government., British Columbia
Not seen since August 2008: Nebraska, Nova Scotia
Not seen since May 2008: Wyoming
Not seen since April 2008: Idaho
Not seen since Dec 2007: Puerto Rico, New Brunswick
Have you ever seen a Yukon plate?
I'm pretty sure I haven't.
