You are indeed correct in assuming that a lot of folks don't want to share the tag numbers on the internet. That being said, a list has been posted a couple of times and I have the names of some of the participants.
I'm quite sure that when we see a Crossfire in the lot at the Grand, it will be looking for us, as for names and such, we just do what the rest of the world does and go introduce ourselves, handle and then our real name.
In these days of internet scams and piracy as well as identity theft, it may be the most prudent way to do this.
You can't be paranoid but you CAN be vigilant. And so it goes, we just try to do the best we can with what we have.
I, personally don't care who sees my plate, I'm a proud veteran and, oh yes, I shoot back!!!
