M1 was in the wrong spot, according to Ohare's site (link below). But I'm not sure how to handle the gates. It seems kind of weird to map the gate ramps since they are made to move. Also, I think gate M3 shares with M2 so it is kind of weird to map. I'm moving M1 but will leave the edit for someone else to verify.
