I was reading about the lifetime permits in florida and I found that if you have a son or daughter younger than 4 years old the lifetime permits are a lot cheaper.

The info is at the bottom of the page.
I almost bought one , but the fwc stopped allowing free special opportunity hunts for those with 5yr or lifetime licenses the incentive was gone. They offered some good hunts a while back.
