I actually just saw a bunch this morning along Flagler in Downtown WPB. I run along there 4 days a week, and have been seeing them 3 out of my 4 days weekly for a few months now. You have a good chance, but unfotunately I can not guarantee. If you happen to be in the downtown Clematis area while in town, I do recommend going out on the new docks that they have nuilt along the waterway and looking around. You will have a good chance at least to see a few. Look for flat spots, as they are usually right under the surface. Keep following it, and you will see their snouts come up for air. Have a nice visit.
