I live in the same general area as you, and starting in the early 1990's we have had numerous lion problems on our property - two cats have been shot under predation permits. The significant rise in lion encounters corresponds to the high level of clear-cutting by Champion and Weyerhaeuser, yielding higher deer and elk populations and hence cats. We ride in the back-country a lot, and I take my 10mm S&W for those outings, or a shotgun with 00. One of the cats that attacked a dog with us looked to weigh at least 170lbs (as compared to a friend's mounted lion).
