Did you know National Wildlife Refuges preserve more acreage than America’s national parks? (About 150 million acres vs. 84 million acres.) I had no idea, either, untilI learned that fact on trip to the wonderful J.N. ‘Ding’ Darling National Wildlife Refuge in Sanibel . And that reminded me of another destination I hope you get a chance to visit — the St. Marks National Wildlife Refuge and Lighthouse , about 25 miles south of Tallahassee .
