Visiting Shark Valley Slough in the Everglades gave us loads of photo ops. I've done the tram tour a couple of times so we decided to walk today instead of riding. We walked out about 2 miles or so then turned back when we realized it would be a 7 mile walk out to the observation tower and another 7 miles back to the Visitor's Center. Saw lots of wildlife including this Limpkin on our walk.
