you can certainly write something like that up if it will make the landowner happy but beware, that a waiver like that isn't worth the paper it is printed on. having friends that are lawyers, it always makes them giggle when something like this comes up in conversation. Now I don't know about your state but in Wisconsin it is state law that any person, while on the land of another while recreating(hunting, fishing, trapping, making syrup) can not hold the landowner responsible for any injuries or other liabilitys. This does not apply if the landowner charges more than $2000 for the activity. This of course being state law give landowners full coverage. I have to bring this up sometimes when asking to hunt on farmers land so thats why I know about it.
