Back TO you.

And here we enter the familiar territory where letters are traded for numbers 4 the sake of economy.

Since license plates have a limited number of characters they can display (usually around 7, I hear) people tend to save space by leaving out vocals or changing certain words 4 their numeric counter parts or shortened versions.

At first I thought this was a dealership loaner but then i figured: "Heck, why would the dealership get vanity plates for a loaner?".

I guess Back2u was trying to let an important someone know something. Or maybe they are involved like Dr. Jazz, in the broadcasting business ("Back 2 U, Katie"). Maybe they like Prince a bit too much and took it a step farther than they should have.

Well, at least it's not a tattoo. Or, is it?
