No, a lot of property owners, farmers in particular are offended when someone thinks they can just buy their way onto the property. Start with small talk and explain your situation and make sure they know that you realize giving you permission is just that, and that you will not bring any un-approved guests who might just decide to return since "you" brought them there. Dont play the money card until you realize its the only thing that will. The veteran status will open more gates than money, my dad is a vietnam veteran and i cannot believe the doors that has opened. Be polite, make small talk.. Your not just trying to gain access, you want to gain a friend. If he says no anyway.. Tresspass and shoot all his cows.. Kidding of course... Maybe..
