I grew up in the area and in my youth and used to get off the school bus early to stop in the nearby convenience store (which was known as the Green store even after they painted it another color) for a drink / snack... and on evening walks with the family, my brother and I would always check the soda machine and pay phone for loose change.
But enough about me and more about the cache... you're looking for a magnetic bison tube, so bring your own pen.
