If you go the Trailside Museum in Milton, MA and pull into the parking lot it will look like this. I used to go here a lot as a kid. They had a pair of otters and a red fox that passed away a little while back. They still have a Snowy Owl and a pair of one eyed Red Tail Hawks. With only one eye the hawks are unable to survive on their own. My wife and I went a couple of times when they had presentations that included a porcupine and a Great Horned Owl. It's a great place for kids. Check their site for hours and calendar of events http://www.massaudubon.org/Nature_Connection/Sanctuaries/Blue_Hills/index.php .
