You're right. As far as I know, there aren't any mosques around that advertise. However, there are many Middle Eastern folks who have gravitated here. Professionals and business owners. We usually keep our eyes peeled for tweekers.
There are next to none where I live, but our local paper has just recently hired someone with an arab name who is writing for them and I am certainly curious. We are a very small city in northeastern upstate NY. In Albany, where my twin daughters live with their families, there are many Muslims. I was down there last week and some girl wrote a letter to the editor about Muslim girls being made fun of because they wore hijab. Of course, Albany also saw a major arrest last year of terrorist abettors.
