I have to agree that most player's (Especially micro limits) go a little bit too much LAG. I enjoy playing during those hours only when there are promotions, ie: Take 2, so I can clear the bonus faster... or like the February $100 bonus that you had to unlock $10 at a time.
Other than that, I chill... I live in Vegas, but I am a total night owl so I do not play with most of the US players... in fact I constantly find myself being the only US person on a lot of tables... normally Aussies and all them people half way around the world and I must say the competition is "fairer".
By fairer I mean that you don't see dumb you know whats going all in with bottom pairs and hitting sets like that... These "foreigners" play a lot better and realistic poker IMHO in contrast to most US players. So when it comes 5 AM my time (08:00 Hours On Tilt) I am out... I start to notice the influx of obviously the east coast waking up and playing.
