What are your best ideas for income generation on large amounts of vacant land?
Suppose you had access to a large amount of land.  Anywhere between 500 to around 5000 acres.  What are your best ideas for income generation?

I would like to think of something besides the usual timber planting, edible crop farming, cattle raising, or simple hunting leases.  Any ideas would be greatly appreciated.

Edit:  I should add that the land would be in a rural area so most residential products wouldn't be feasible.
