I'm in a tough position because 2 years ago I had found a cow stuck in a big mud pit on a guy's property. He was there the whole time and after we got it out he determined it would not live and would need to be put down. I offered to do it (since I was armed that day). He then told me that I could come hunt his property for ducks. Regrettably, I never took him up on his offer, and now, two years later, I really want to try it this year. How should I go about asking?
