I'm one of those. No dry hops, no secondary. But if I plan to dry hop, I'll go 3-4 weeks in primary, then rack to secondary and dry hop. I prefer the results from doing it that way.
Denny I'm somewhat surprised by how long you leave your beer in the primary. I understand that there isn't a problem in doing it, but I find myself wondering if there is a benefit (other than ensuring FG).
