About 2:30 this morning, the dog started a frantic bark, ran to every door in the house and kept barking. I looked out the window, and saw a black bear coming out of the cabin and leaving the boat via the swim step. Shotgun in hand I inspected everything, other than tracks nothing much happened. I am pretty sure the dog heard the bear going up the boarding ladder. I raised the boarding ladder and went back to bed. Thanks to Dusdee for keeping watch while we slept. Otherwise there would have been a mess to clean up.
