I have a small suitcase full of a great variety of wires. Some people collect stamps or coins; however, I collect wires and their connectors. My treasure is seldom used because every time I require a new connection, I never seem to have what is needed. This allows my cache to grow larger by the year.
I've noted one interesting thing about my hobby. Age seems to have made me more of an earnest wire connaisseur. Whereas I used to assume anything between the two ends would work, now I'm a lot pickier. The quality of my cables has steadily improved over the years.
