Yes--we are on the far end of the eastern time zone--so it is dark now. (don't know when it got that way but around 8ish it is twilight/sunsettish/getting darkish).
I know when we went to Michigan one summer--I was shocked they coudln't do 4th of july fireworks until after 10pm b/c it didn't get dark until then.
Not sure if it is that way in MN as well.
