I carried a Canon EOS-1Ds Mark III and EF 300mm f/2.8 L IS II USM II Lens through Corkscrew Swamp Wildlife Refuge, but fortunately had the small Canon PowerShot G1 X with me for some interesting scenery shots along the way - including the lichens-covered boardwalk.
Corkscrew Swamp Wildlife Refuge is a great place to visit. Painted Buntings, Little Blue Herons, Egrets, Alligators of all sizes, a Cottonmouth Water Moccasin and more landed on my "what I saw list" during my short visit.
