Looks like this thread is running 70-30 (didn't count) in favor of the night owls. Put me down in the "Happy Morning Person Do You Want a Cup of Coffee!!!" camp. It may have been learned behavior when I was 19-20 and expected to be on the job site shoveling sand in the mortar mixer at 7 am before the surly, possibly hungover, bricklayers arrived at 7:30. I quickly learned that putting the alarm clock on the bedside table was a no go. Put it on the dresser on the other side of the room so you have to stumble over there and shut the dang thing off. No snoozing that way.
Of course, that meant a reasonably early bedtime. Man, did I miss out on some heck raising partying! It also meant I (mostly) missed out on the lawn puking, girl friends throwing dishes, cars in the ditch, DUI's, and fist fights. Win-win for everybody, cause I would have kicked their ***

, except I was in bed. And I brought home a pretty good pay check for the day.
I guess I never got over it. Now in my leisure years I find that I get up when it first begins to get light, make the coffee, check the email from evil night persons, check the forum, bring in the day's firewood, let the dog in and out three times, check the weather forecast, have a third cup, watch the sun light up Ice Mountain, wonder what I'm gong to do the rest of the day. Something usually comes up, but there might be a nap involved.
Besides, who wants to miss a sunrise like this


?
