Almost every state has a bunch. I specifically mentioned those three because they’re mostly unique.
It is, it’s one of my favorite pastimes. Although I’ve never actually visited Everglades National Park because apparently my parents couldn’t find the entrance. I should go on my own sometime, but I usually visit state parks instead, since they’re closer and cheaper.
Everglades sounds like a great place to go and I want to go as soon as I can since I’ve been hearing statistics and testimonials that it’s shrinking and it’s going to disappear in a couple of years.
