klhansen - I am sure that goes on quite often in the great white north of Alaska. Not so much around Paulaskifield, Missouri.
Down here in much of the lower 48, given warmer temperatures, the engine generates enough heat to keep the thermostat wide open whether you're climbing a steep grade, at idle in traffic, or moderate speed on flat ground.
The main goal of the thermostat is to attempt to prevent the engine from falling below the optimal temperature for ideal performance.
The OP was concerned about his maximum temperature which a thermostat has no bearing on unless it is stuck closed.
