If your not going to show your car for judging purposes, then there's no need to register. You will not be able to park your car with the registered show car's lined up, however there's plenty of space for those coming to see the show.
Now, if you want to register and pay the $35.00 (which includes a T-shirt with the event logo and date) and you park your vette w/ the show vettes, but choose NOT to be judged...that's up to you. It's not mandatory your car be judged.
But, if you've never had your car judged...............get your feet wet..
Not sure about Dash Sign's for w/ your name. Think Jim Kill made mine up and posted link?
JIM KILL..can you help out here?
