I'm with the second part of Quiltsfor's post. Just pick a time and leave it there!! But I would prefer staying on DST all year round. When the kids were in school, I would worry about them walking home after game practice (no second bus) in the dark at 5 p.m. And in the mornings, their bus was so early that it was still dark even after the time changed.
I grew up in Saskatchewan and that province stopped changing time back in 1966. It did not cause the cows to stop producing milk, or children to dose off in class (any more that usual that is). I believe the original reason for the change in time was to save electricity, which makes no sense at all to me. If it is dark earlier in winter, more people will be turning on lights etc. in the evening, than would not be using lights in the morning because it is brighter.
