found two perfectly preserved (and completely dried out) oranges and a pepsi can with a pull top in an access panel of a hi rise office building. the building was built in 1973. i guess it was somebodies lunch during construction. the best thing i ever found was an american standard cap on top of an air handler in an attic. i left it there accidently 6 years before. 140 degree attic during the summer, i wasn't interested in going back for it at the time!
