Personally, it doesn't matter a whole lot to me. I wake up with the sun, whenever that happens. Right now it's around 6:45-7:00am. In the summer, it will be closer to 5:30. Right now, I'm ready for dinner at 4:30 and feel like I should be in bed, but look at the clock and it's only 7:30pm. Ugh. In the summer, dinner could be as late as 9pm. I'm totally driven by the sunrise/sunset because I have no reason to follow a clock.
I do enjoy a longer pleasant summer evening, but in reality it's so damn hot here you're inside anyway.
