Women Traveling Solo but Savvy

In my zeal to be a well-prepared traveller in Europe I've enjoyed pouring through this terrific site: www.ricksteves.com It has been informative in the extreme and on the subject of women travelling alone in foreign countries -- even comical.
Under the heading of Dealing with Harassment I discovered this gem:

Wear a real or fake wedding ring and carry a picture of a real or fake husband. There's no need to tell men that you're traveling alone, or whether you're actually married or single. Lie unhesitatingly. You're traveling with your husband. He's waiting for you at the hotel. He's a professional wrestler who retired from the sport for psychological reasons.

So, what do you say folks? Got anything more compelling to offer me?
