Just recently picked up a new machine and hammered up two more nails for the keys to it and wondered what other Pinsiders do with their keys. For me I've got them all lined up and the keys on the right are for the backboxes and the left are for the coin doors, makes it nice and easy if I ever need a key. Also put all my keys on the plastic key fobs.
Are you as anal as me with how you keep track of your keys? Do you just throw them all in a bowl, just leave them in the machine, put them on the plastic fobs, have a cool thing you've built to hold all your keys or do you have one giant key ring that's the ring to rule them all?
