Loving the herd life
Around here they are free if you go pick them up. I've found them on Craigslist (both by putting out a wanted ad and by watching free ads) and companies that lay the cable often have them laying around. I saw some in a field one day (at a business, not at a farm/personal residence) so I stopped and asked - the guy said take whatever I want.. he didn't know what to do with them.
