I've not worked on cemetaries during my years as a planner....However, when I was in school in Boulder, CO, many years ago; the in-town cemetary was used as a frisbee golf course...AND.. when I took geology, we had our final exam at the cemetary. You were given a list of names and you had to find the tombstone and identify the type of rock from which it was made. Unless using cemetaries for leisure activities is frowned upon as disrespectful in your community, there are many ways that you can integrate the history with leisure time and open it up to a world of interesting grant possibilities.
