Homosassa State Park - it was a bit of a drive (we had a rental car), but it was an awesome day.
Thank you so much- yes I suspected it would be in that direction. We are driving from Orlando to Palm beach shores and I am so hoping to spot some manatees toward the Eastern side of the state. It will be in October and so the waters will still be warm out in the ocean. Therefor they are less likely to come inland. Here's hoping!
