It is absolutely necessary to have daylight in the morning to get to work and school. DST all the time would make several months in a year where it would be dark in the morning during commuting time for workers and students. As a substitute teacher, I am effected heavily by this, and in our town, so are a great many of the residents. I would prefer a constant time to be standard time. Then, at least for school children and related professions, it would always be light for the main academic school day.
If we went to DST, I would recommend that the school day be changed to at least an hour later, and work days also start later, to accommodate the light.
