A couple of the providers I've seen out that way a while ago both spoke about how the LE goes to hotels with some type of lists of ladies to be on the lookout for. They are all trained to spot suspicious things. Sioux Falls is a "big city" around the area, and it's often a quick stop for people on their way to (wherever).  One provider I've seen here in Mpls said she will never offer services in Sioux Falls due to the high presence of LE.  She said she almost got free room and board for at least a night on a couple different occasions due to this....  

I don't have anything thats happened to me directly, but I heard enough to leave it alone
