yeah, Montana was 'safe and prudent', but that only applied to certain areas and during certain hours, then it was 70 or 75...
last I heard, the 'no limit' was lifted...
i really don't see the point of a limit on a well maintained 4 lane highway where you can see for miles as long as the car is built for it. Americans think going 140 is nuts, yet in Germany, 140 will get you flashed to get the hell outta the way, lol
oh...by the by

*The 55 MPH maximum speed limit is still in effect in Florida except where otherwise posted. *Speed limits are 70 MPH on
some rural interstate highways. Speed limits may be changed on other multi-lane highways and in areas where the conditions require lower speeds. Drivers should not assume because the area appears to be a particular urban, municipality, business or highway area that the speed is the standard or expected speed zone. Observe and obey the posted speed signs as there may be frequent changes from area to area along the selected roads or highways.
