Not where I live. I am quite far from Rapid City and Sioux Falls. The Muslim population is concentrated in those 2 cities. Our SD house is at the extreme Western edge of the Cheyenne River Sioux Reservation. I do not know of any Muslims in Ziebach County except for my wife and myself. However, we find many seekers that frequently request information about Islam from us.
We also spend a lot of time on the Pine Ridge Lakota Sioux Reservation. We do know 8 reverts there and many seekers that seem to be sincere in learning about Islam.
We do know a few Muslims in Rapid City, but sadly there seem to be a recent expansion of a group calling themselves Muslim, but not acting very Islamic. The only Masjid is in dispute as to who the legitimate Iman for it is and the Masjid is seldom open even for Jummah.
Sioux Falls has a very nice Muslim Community and There are even Muslims as far North as Brookings. We usually go to Jummah there.
