Returning home yesterday, ATIS says winds calm and I'm south of the airport. Tower says "make left DW for 18R." I read back and then ask if I can use 36L. Tower says "Ahhh, wait one." Then comes back on and says "With the plane doing T-N-G's on 18R we can't have opposite traffic on the parallel." I could tell in his voice that he was repeating what someone just told him. I repeated my landing instructions to 18L and landed. I guess this is the Harrison Ford-lining up on the wrong runway and all the problems that would cause prevention method.
