An equally odd rule here in the state of Florida is this..

If you are crossing over protected land where fishing is not permitted and you have fishing equipment on you (Even emergency kit based) you get fined. A friend of mine was doing a thru hike from Alexander Springs through Juniper Springs and into Hopkins Prairie. Along the way you cross through three areas. He's a fisherman and planned on catching fish to eat once or twice on the four day trip, but if he had been stopped on those selected parts of the trail that are protected lands...he would've been fined. Which is a bit silly.
