Do anyone have any advice how to keep these geese off your property and really off your lake. We string 30# fishing line around our property but they still get in, eat our new grass, and then crap all over the place. I know they are federally protected and you have to go through the DNR just to get permission to scare them by firing a shotgun over their head (which does not work), but there has to be a known way other than outright murder.

Has anyone tried any of the following?
