Dolphins!

In 1996, I fulfilled a lifelong dream by swimming with dolphins for two days in the
Florida Keys. It was magical. I wish I could do it every day!

If you would like a dolphin adventure of your own, I highly recommend Dolphins Plus, located in Key Largo, Florida. They accommodate persons of supersizes, like myself, and have wheelchair access. They also have a platform that lowers and raises one into the water, so one doesn't have to worry about how to get in and out of the enclosure. If stairs are a problem for you, let them know in advance, and they can take you to the site via a different route than the rest of the crowd.

You may jump directly to their web site from here: Dolphins Plus, or contact them later at http://www.pennekamp.com/dolphins-plus/.
