I agree 100% and add the advice that you should NOT buy those novelty license plates which support manatees or other conservation efforts. Because, some of the funds go towards restricting our access to national parks, state forests and our waterways. For example, monies from those manatee license plates pays for more no wake zones to be instituted. If you must have a novelty plate, buy the education ones or pro/college sports teams.
