You could also use a fishing rod with 20# line and a heavy floating lure with hooks removed to prevent from hooking a goose. Practice your casting and try to put the line over as many geese as possible.
I really really really like this idea! Just think of the fight you'd have on yer hands if that line got snagged under a feather or two!....I'm thinking 30# line!
Dang Esshup! You may have just invented the next great water sport!
