We had no worries at all about our safety on our airboat tour of the Everglades. The boat was equipped with floatation devices and first- aid supplies, as well, so we felt like we were well prepared if something did occur. Not only did our captain ensure our safety, but also he was also a great tour guide and shared many details about the ecology, animals, plants, and history of the Everglades.
