Friend's Father came out his garage and saw a black bear about 15 feet away. Though not a problem as it is not unusual. Then he noticed it had cubs. He sat in the garage for the next two hours till they went away.
I saw a shark, about 4 foot long, made me a faster swimmer than Micheal Phelps and a small 'pouch' than Thoma Daley. There had never, ever been a recorded shark attack on the island I lived on.
Saw a lone barracuda some out the murk after a storm, that was really scary as I was on the ocean side of it and had to just wait it out till it went away. There had been several barracuda attacks, luckily they are the Atlantic ones, so not too bad, unlike the Pacific ones which can really bite a large chunk out of someone.
