How to tell if local laws against crossdressing?
So it doesn't sound like there are any states that have laws against crossdressing.
I get the impression that some small towns still might have them and actually enforce them.
What's the easiest way to find out if a town has such laws? Do you have to contact the police department and/or city office?
It wouldn't be fun to be stopped by a police officer while dressed and discover it's illegal.
They don't need no stinking law against crossdressing
There doesn't need to be a law against crossdressing for Law Enforcement to make your day a real challenge. There are lots of very vague laws concerning Public Indecency, Public Disorder, Obstructing Justice, False Information to Police, as well as the need to determine if you are any kind of a threat to commit a crime. Officers have a lot of discression if they want to get involved in your life and you are in a public place.
Now, most of them are too busy and/or just don't care enough to go out of their way to do any of that, but it doesn't mean they can't. My suggestion is to behave yourself, don't drink and drive and if you become the subject of an officers attention, cooperate as best you can. Have your id ready to hand over, even if you don't like the picture. The statue books are very thick and they can be very creative in the application of some of those laws. Even if it is thrown out at a later date, your world has become miserable when all you wanted was to enjoy a little time out.
