Interesting that you got an antique license on a vehicle that was made from so many different parts. I'm not saying that you shouldn't have. I just find it interesting. So, technically, you can only drive it to "exhibitions, club activities, parades, and other functions of public interest," and can't drive it for regular transportation. Cops around the Dallas area are pretty picky about antique plates. If you can't prove that you were doing one of the allowed activities, they write you up.
