Not to deflate any hopes - but we had bears come up to our patio ( no we don't feed them ) with 15 of us eating and talking. The bear got to about 10yds. and several of us got up and rang a metal bell we have outside, ( it's loud ) stomped our feet and yelled at it and one guy bluff charged it. It ran about 40 yds. and came easing back in like a scolded pup !! It's not like OUR food was the only food around the area. The other camps in the area and ours all plant corn, all kinds of food plots, apple trees, etc. So Mr. Blackie wasn't starving - but he sure showed us how determined they can be when they want something. Flashing light ........... not THAT one. We need an airport tower beacon with a tornado siren !!!
