Join us for a Lecture at the Lagoon and hear from a variety of interesting environmental personalities who happen to specialize in telling stories about really cool things. Fascinating topics range from the octopus population under the Blue Heron Bridge in Riviera Beach to why manatees really matter. Everyone is welcome on the first Sunday of the month, and other Sundays as noted on the calendar. Talks are scheduled from 2 to 3 p.m. with time for a question-and-answer session afterward. Ample seating is provided. Advance registration is encouraged, but we welcome walk-ins as well.
