On my thru-hike, I saw bears in Shenandoah, Pennsylvania, and New Jersey.
However, I've seen dozens in the low country of the Smokies on both the Carolina and Tennessee sides. I also saw bears in Georgia and Tennessee a couple of years ago on the Benton MacKaye Trail.
I encountered one bear in Yosemite this past summer. Several in Wyoming. Also one Grizzly in Wyoming and two in Montana while trekking the Absaroka Range.
