I couldn't agree more. I am in Indiana and ever since we switched to daylight savings I have hated it. There is no real reason for it to be light until 10PM....I have an 8 year old and you are so right in it disrupting sleep patterns. Who wants to go to bed when they can be out playing?
Selfishly, I also like when it gets dark early..I've always been like that. I dread the coming of daylight savings every year!
