Phreaking Payphones....yeah me and my friend Hotrod use to do it, but the knowledge was all on his side. I let him do the work...wasn't to interested in it at the time but i regret that now. Gizmo use to call me with Optix on some party line...they did some crazy stupid shit on that line...some thing with airports and bagage and scaring people...use your imagination...they were scary.
