I only just moved here and have heard all the horror stories.
But The one cruise meet I have attended was organized on FB across several club pages, had at least 100 cars attend and I did not see 1 police member.
Heard about someone who was pulled over while driving but that was not on the designated route.
Not saying they won't, just sharing my first cruise experience.
I do agree that location should be not too hugely published, but how do you know who is and isn't going to inform them anyway.
And as said, be responsible and its all good =)
