While cleaning out my vintage minivan, I ran across some Clif bars which I had stored under the front sat and opened one. It was noticeably drier than normal, obviously losing moisture due to the frequent high daily temperatures in the interior. As the deterioration of the trim of this vehicle will attest, it was typically parked in the open, exposed to the blazing SoCal sun. The bar was edible, but I would have preferred a nice cup of tea in which I could have dunked the bar to restore moisture. The bar had a sell by date of June, 2002. Had it been stored in better conditions, I doubt it would have been noticeably altered at all.

Any other experiences with archaeological Clif Bars?
