As far as traveling to meet potential marriage mates was concerned, I heard this was done a lot. However, there was definitely a bias against women. If a woman visited another congregation for a reason other than "finding a mate", for instance, maybe you were visiting a relative in another state, people in the congregation looked at you with a jaundiced eye. You could see the married women holding desperately onto their husbands (how pathetic). They definitely looked at a single woman as somebody dangerous and made her feel unwelcome. Some Christians!
