Hi,
As someone who has lived in the country (Catskills) for most of my life, a gift certificate to a restaurant in my opinion would come across as a blatant bribe, and who knows what particular type of wine or whiskey they like, if any? Even if they bake, a homemade pie is the nice, neighborly, friendly thing to do and will get you a long ways towards friendship with country people, trust me. You could always buy one from a good bakery and it would have the same effect. How about one of those NY cheesecakes!
Which is what you want, to come across as a nice guy or woman who they would feel happy to deal with and have on their land, not a city hunter looking to bribe them off so he can use their property. Of course everyone' s different, that' s just my respectful opinion from experience!
Good Luck,
Mark
