Was thinking about this the other day and thought I'd ask your thoughts. You can fly a plane in to anywhere you can get to and just have to wait a bit before hunting. Why not helicopters?
Is it just one step too far in terms of making otherwise inaccessible areas accessible? After all, you only really need a small clearing...as opposed to a decent sized lake or landing field of some sort for planes. But if you had to wait long enough....
Saw Newberg's copter hunt - that's what made me think of it.
