This cache is hidden in the Audubon Sanctuary located off Burr Street in Greenfield Hill.
This is a nice, quiet place to stroll, enjoy nature, and do some bird watching.
Take some time and explore (if it's open) the bird rehab area. There one can usually find a red-tailed hawk, or an owl or two, being attended to by the staff..
Open 7 days a week, sunup to sundown. Free for Ffld residents, but I never heard of them charging anyone money to get in...
