I live adjacent to a National Park. I have looked up from bush hogging my lower pasture to see people riding horses on my land on the way back from riding in the Park.
I greeted them with happiness because they are my neighbors (and their friends) and we have lived next to each other for 30 years, We are not even sure where some of our actual boundaries are. But when I get stuck, they pull me out and I bring them pies. We are fond of each other and help each other. Having good neighbors is worth an awful lot.
Can you imagine a situation where you can benefit each other? It sounds as though the slate is clean and you have the opportunity to make it work for both of you.
