I think we should change our clocks four times a year to keep the time it gets dark in the evenings more consistent. 7-7:30PMish. Here in STL in the Summer it gets dark at almost 9PM and in Winter 4:30-5PM! If we adjusted clocks on the Equinoxes and Solstices up-an-hour, then back, then ahead-an-hour, then back it would equalize the getting dark times a lot more.
