I've never read any of his collections, only poems picked up from here and there. (And The Cremation of Sam McGee, obviously, in childhood.) I find Service boring when he talks about women (I find he has an internalized misogyny of sorts, sadly) and war (not a topic that really stokes me), but of course he absolutely soars when he talks about the wilderness. Because that's a place where gender and wealth and infighting and belongings don't really exist, and that's where his writing flies.
