Southwest City, Missouri is in the southwest corner of the state, and this marker proves it. Mike Dietrich describes the view:
I am in Oklahoma, my car is across the street parked in Arkansas which is the parking lot for the Phillips 66 gas station in Missouri. Much like the 4 corners, the "tradition" (according to the clerks inside) is to walk around the circle of all 3 states. Ahead you can see the sign and beginning of MO 43.
If you look closely, you can see that the marker also shows the years that Oklahoma and Arkansas became states.
Mike also took another view of the marker (below), this time from the Missouri side.
