When traveling thru Dallas awhile back, I picked up a copy of The Muslim Yellow Pages, out of curiosity.
There were many, many pages of listings for businesses like this, as well as listings for one-day passports, identity documents, travel agencies, etc. catering to the special needs and habits of Muslims.
The sheer number of mosques and schools in the Dallas area blew. my. mind.
If your city has a Muslim Yellow Pages book, it’s worthwhile and eye opening to get one.
There's a newly built large two story mosque about 3 miles from my own house.Construction completed 15 months ago. I drove by it and it looks to be about 20,000 sq feet with a tall, thick solid steel gate all the way around it. And a muslim 'guard' at the closed gate.
