I recently bought a humidor and cant seem to get the levels to get down to the desired 65 to 75 range.

I did everything that instructions said to do but it stays around 80 all the time unless I open it and leave it open for a while. Any suggestions would be helpful. Thanks!

This 1974 film, directed by Joseph Sargent, is about 4 heavily armed guys who hijack a subway train in NYC. It stars Walter Matthau, Robert Shaw, Martin Balsam, and Hector Elizondo. Matthau plays the head of the NYC transit police, and Shaw the head of the gang. Dick O'Neill and Jerry Stiller also co-star. Even Doris Roberts has a small part in this film.

The gang quickly and precisely makes their demands known. They have hostages, and seem serious to carry out their threats. ...
