They have been doing the same thing here in la. for as long as I can remember. Heck when I was in high school I was good friends with the head honcho at the NWR down the road from my house and I would go with them some nights. They would shoot does and occasionally they would shoot a few mature bucks to test for disease. That's when I realized how many nice bucks were out there in the marshes that you never saw in the daylite.
