Cousin and my last deer lease was a "serious" compound. A 1700 acre pasture, a dozen box stands, a 3BR trailer for sleeping, another trailer for cooking, a mess hall, storage, and a place to sleep guests, and an ice house, and finally a fleet of jeeps that usually needed repair. Rifles, shotguns, handguns, fishing tackle, and stuff to support year round enjoyment. I think that is what you are alluding to as serious.
On the other hand, when I was making entry level pay, had a wife and two young daughters, day hunted as invited, used the company car back and forth, and hunted with a borrowed gun, that was SERIOUS. My family needed the meat! I generally took my limit in does or fork horns. They are better eating.
Just my take on the reality of life.....
