6am is a going to bed time in Vegas FFS............
In the very old days, bed time was something that happened every 2-3 days, at whatever time of day or night I finally couldn't see.
In the old days, 6pm was going to bed time. Wake up at 1-2am, go and jump in amazing games that ran all through the night.
More recently, the games are more likely to break up, so now I am more likely to play golf/laze by the pool in the morning, poker in the afternoon, dinner, then go and get drunk and be in bed for 2.
