There are all sorts of "Springs" around this area - some are warm, some have high mineral content, but mostly they produce millions of gallons of fresh water daily. The Manatee Springs are famous because the warm temps attract Manatees during the winter chill. The day we were there we did see 2 manatee - no photos, sorry!
But, we did get photos of a true Hitchcock experience at Manatee Springs.... it turns out that Manatees aren't the only winter visitors! - it was unbelievable!!!!
I think the real State Bird of Florida is the Black Vulture. We saw hundreds.
