OK, I'll play too...
If you use the simple $$$ out vs. land size I'm at about $1400 / acre.
But that doesn't take into account the fact that over the 6 years (! - time flies!) I've been using my tractor I've not had to pay someone $1500 or so each year (had to do it one year) to clear my pasture of tall, dried weeds. (This is important out here in California, you know /forums/images/graemlins/blush.gif). I've also used it to maintain my various driveways - if I didn't have it I'd either be paying to have it done or drive on really nasty dirt trails.
So when you factor the purchase and maintenance costs over your period of ownership and then deduct the money you *haven't* spent on getting required work on your property the real number goes down real fast.
Oh, sure, I could just be trying to justify it /forums/images/graemlins/grin.gif...
