Found a good deer trail with lots of sign, then bumped a bear who was walking up a trail that intersected the deer trail. Berries all over and TONS of bear sign. Gonna set up at the intersection. I'm using my Selfbow so my longest shot will be about 20 yards. How well do bears see? Enough that I'll need to sit in a brush blind with my ghillie or would just sitting in my ghillie be good? Or is he gonna see me more then likely on the ground and I need to find a tree stand. I've never hunted bear with a bow, let alone a primitive set up like this so I'm kinda unsure about the whole sitting 10 yards from a bear thing.
