I was recently on a service call and found 6 partial bags of 12-yr-old Mary Jane in the bottom of a Millipede. The guy used to hide his stash in there, would forget he still had some left, get a new bag, repeat. There was also like 13 lighters in there. He quit smoking when he got married 10 years ago and forgot all about it, until I opened it up.
He offered to let me have it, but I don't smoke. Still I have a friend who does, so I took it and gave it to my buddy. He pronounced it to be very dry but "still good"...
