Oh! Yeah, many people think of puffins when they think of Maine. Now that I think of it though, it has been awhile since someone has asked me if I've ever seen one.
I have seen moose and black bears. There's not as many moose around as there used to be, but once, many years ago in less than two hours, I saw over 20 moose. This year, I've only saw one so far, and that one was when I was out on a four wheeler and it was standing in the middle of the trail while I was on my way home.
On black bear, I've only saw a cub, but that doesn't mean I haven't been closer to the ones I didn't see. At least once, while I was out in the middle of nowhere, one was between me and my car, and I know this because only a black bear smells like a dumpster when there isn't one in a hundred miles. Then there's been plenty of camping trips that they were sniffing around my tent at night.
