I have to say DMV in CT went from horrible to pretty good.
Going there used to be a whole day trip with sketchy results. Now, you hardly ever have to actually go there. Most of it can be done through mail/online.
And even when you do go there, their new building in Bridgeport is pretty good. They have a nice little set up.
Compare to what it used to be in the 90s (East main street).....it's night and day.
