Coach, I have a place where I store my osage. Dark, hermetrically sealed, behind heavy steel doors. Ralph and Terry tried to get in there one day in Norman while I was working a game but didn't succeed.
I cut all of mine, seal the ends, take the bark off and keep in my garage or shed where as little light as possible can get to it, and cool to prevent moisture from escaping too fast. Never have any problem with drying checks.
I wouldn't charge much for tending to your osage stash until it was ready to make a bow.
Mike
