I hope some day to have enough land to do some QDM in my retirement...although in my case it would be more on the order of 100 acres so my ability to QDM would be limited without neighbor help.
I don't really like the idea of an enclosed shooting 'house', as that really would seperate me from the nature I so enjoy when hunting.
If this guy is doing this without high fences and making a buck selling hunts to wealthy clients, more power to him.
