Our lead is a local/regional alternative energy contractor (does residential to large-scale commercial - not industrial - solar and wind system installations). A 100-foot long scrap of vinyl coated HW cloth 18" high is worthless to them. Yet that one scrape can create a skirt to keep voles and shrews out of my whole chicken run/garden! And that was just a small portion of what we scrounged. If you can find someone like that, you're golden! Another perk from them: all the free brand new pallets we can handle!
