Rule #1
Never, never, ever bring home a box that contains or contained a new toy that you have purchased without the wife knowing about it.
Case in point: I bought a brand new Lone Wolf Assault stand. Went to my archery shop, promptly pulled it from its box, handed the box to the shop owner and said "Burn this. I was never here". I left the shop, snuck into the house through the basement and made haste to my "man cave" where I leaned it against the wall with other miscellaneous hunting items. I placed a few shed antlers and broken arrows around it to make it look like it had been sitting there for a while.
I can only speak for my loving wife, but when she sees a treestand, bow, etc. sitting in my cave, it's just more of what she calls "The Circle of Carl". However, she has a very keen radar for new boxes and if she spots one then the questions (interrogation) begins. This is when I go from predator to prey. Don't let this happen to you! Best of luck and may cunning, stealth, and a lot of luck be on your side.
