I always scout before asking so as to not beat myself up in the asking for marginial properties. I ask for permission for "waterfowl and doves and ground hogs an stuff like that." Asking for permission for deer up here is a usless cause.
I also offer a release of liability form as soon as they start thinking. It goes a long way when they know your willing to offer it.
Offer to help them out and tell them to call you if they need help around. Most will not but some will.
