Going up the hill, the grade increases as the city center comes into view. Just at that point the limit changes from 35 to 25. Reasonable, yes, from a traffic control point of view, but most people instinctively resist decelerating on the upgrade, and many tourists get it right there.
Going down the same hill, there is a sudden drop at about Galena Street.
That’s where the radar is, in the free fall area.
Counting the 50$ fine and the three year insurance penalty, my last
30/25 going up cost me $650.
