Depends on the day and the event. At the first Socal Herf I started at around 4 a.m. on Saturday (on the way to the airport) and finished at 4 a.m. on Sunday, on my way back to LAX. During the course of that 24 hours, I had 23 cigars (not all were smoked to the nub and most were tpc's or pc's, mind you). I'll admit the last few were not nearly as good as the first few, though. But, to say I didn't enjoy them, would be false.
In general though, one or two a day unless I'm at a herf, then 7-8.
