U. S. 287 and U.S. 54
Proceeding south on 287, I turned into the Shell gas station on my right on 287. Exiting the station I crossed 54 to make a right turn onto 287. There is a curve leading to the expectation of a yield sign. Looking for oncoming traffic on 287 I did not observe that there is actually a stop sign. $133 cost. This is similar to the preceding entry but seems to show that the trap works for any turn at this intersection.
