A special plate, like my lobster plate, is like $20 a year. The money helps the fishing industry. It always goes to something, it's not just a state fee.
That's cool. My mom got my dad an owl plate at one point when we were in PA but I could swear it was just a one time payment to get it. That was back in the late 90's though.
I'd like that manatee plate, I just really hate adding extra (non one-time) payments to my life. God knows we all already have enough of those.
