I have no doubt that hanging squirrel will dry it out, but aging a big game animal covered to keep moisture in and aging a squirrel in water are two different things.
I'm not being intentionally argumentative, but aging, tenderizing, brining, and marinating are scientific processes, of which, many (unscientific) myths exists. I am unfamiliar with the science behind aging in (plain) water. What happens during these 4 days and what is superior about it compared to brining?
