I wouldn't count on the GW's 'looking it up', as the law states that you must have a valid fishing license in your posession..
from the WLF website:
http://www.wlf.louisiana.gov/licenses/fishing
"A recreational fisherman must purchase and
have in possession a valid basic recreational fishing license to possess fish in Louisiana waters or
to use the following:- Bow and arrow
- A barbed or barbless spear
- Frog gig/catcher
- Scuba Gear
- Hook & line (trot line)
- Cast net with a radius not to exceed 8 ft. 6 in.
- Rod and reel"
I'd think she's ok this weekend with the free fishing weekend, but come Monday,
