I play 3/6 at the Commerce Casino and you can definitely make some $$ on the weekends. I've been averaging $50/hour for the past few weekends because there are so many loose/drunk players that call down to the river with weak hands and the "any two cards" mentality (especially Saturday night). I've probably been on an up streak, but the 3/6 game is pretty easy to beat consistantly. Even so, the games are much quieter during the week, and grinding it out at the low limits seems like drudgery. It would make sense to move up to at least 4/8 as you would make 25% more money and the game is just as easy to beat.
