The problem for me is that at this time of year is that sunset is at 7:30 PM and sunrise is 7:30 AM. That makes 12 hours of tent time. In the summer time the bugs are bad and being outside of the tent is not a pleasant experience. If I fall asleep at 8:00 I know that I will be wide awake at 3:00 and just stare at the ceiling until I now have to get up to pee. Easier to just read or listen to the radio until 10:30 and I will still wake up at 5:30 which is my usual sleep cycle but that is better than spending 3 or 4 hours waiting for daylight.
