This meeting is mentioned in an article about a petition against herbicidal spraying, and in the article it states people "can email comments if not able to attend, to Commissioners@MyFWC.com".
Might be worth the effort to at least send the mail if you can't attend.
FWC has ruined nearly every lake in Florida by decimating all vegetation. Please take 5 minutes and send an email. Lake Okeechobee, Istapoga , Kissimmee, all the way to the St Johns has been turned into a mud hole. Its sick what the FWC has put on their agenda.
