Hi. Minnesota State laws preclude no limit ring games. The two big poker rooms near the Twin Cities (Canterbury Park and Running Aces) both run Limit ring games, Spread Limit ring games, and a variety of NLHE tournaments. Of the two I prefer Canterbury but both are pretty nice rooms to play at imo. I haven't played in a tournament at either for quite a while so I can't give first hand information on the size/quality of the fields.
