I have to say I agree.  A humidor is the best and only way to store tobacco long term.  I have said it before how easy it is to make one.  I have bought loads over the years from paying silly money for my first and peanuts for my last.  I also have a couple of home made ones that really are the best.  Fill a jar with boiled and cooled water, pierce the lid with lots of pin wholes and place in a large sealable container and surround by snuff.  Every 6 months change the water.  Simple and perfect.
