akirlu went and found an interesting page for me.

http://www.carefreelifestyle.net/ has info on renting a Gulfstream V. They don't give a specific quote, but this page puts the GV in a bucket of other jets called "Heavy Jets", and says they go for $3800 to $8500 an hour.

As already mentioned, DC to Morgan City, LA, is a trip of just about 1000 miles, and the GV has a cruising speed of 560 mph.

So for a round trip, we're talking $15,200 to $34,000 (four hours flight time, two each way) for each plane. That leaves aside such interesting questions as whether the jets would stay at the Morgan City airport while Messrs. Cheney and Scalia were hunting, and whether they'd get billed accordingly, or if the jets just made touch-and-go pickups.

I'm not saying these are precise figures, rather they give a ballpark for what it would cost for you or me to do something similar.

Plus whatever value you want to put on the actual duck hunting time, on Mr. Carline's Diamond Services property.
