Yes, most grave yards have some spirits in them. I don't know if your
liquior store would be too good of a choice since I don't think they
carry the right kind of spirit. Any known haunted locations. In terms
of hooking it to the computer, that isn't while recording, just
download the audio to the computer when you are done to review it. If
you have the proper software, you can easily go back if you think you
heard something, etc. If you don't have such software, you can listen
through headphones on the headphone jack of the recorder.
