That's misleading because there are hours of twilight or "civil daylight" after sunset and before sunrise. In actuality, it doesn't get dark.
The exception to "doesn't get dark" depends on the weather. If it's cloudy, we have something approaching darkness. But, if it's clear, there's no darkness right now.
I have made it a practice the past few years to go kayaking at Tern Lake at midnight, much to the dismay of the idiot seagulls that nest there and dive bomb me, trying to run me off.
Today is cloudy, so I probably won't go. If it clears off late this afternoon as we expect, I'll be there.
