a charter boat used to cost that per person, you need 4 to 6 people tho depending on the size of the boat. thats a more personal fishing trip tho. its just your group.
NJ is still cheap, used to see this boat all the time when i had mine. 42 for an adult. http://www.seahunter.info/schedule.html
Fl has some damn cool fish to catch tho, so 80 for a day on the water in Fl aint to bad to me. id give my left nut to go tarpon fishing.
state park camp grounds run around 20 to 30 bucks a night to pitch a tent. have showers and all that stuff. you not supposed to drink at the capm ground so if you do keep it under control, cause they will kick you out. hide the beer cans, drink from a cup you fill in your tent, yeah its that bad.
