as kid growing up on a ranch we used wire in our hay bailers, now it seems like all the balers use twine now, back in the day we only used twine for round bales. The are other wire out there mainly for tieing rebar together its not the right guage. The nice thing about old school bailing wire is I could take a pair of pliers and twist the crap out of it till it was mega tight. Now I can't get any without spending $150 for an entire box. any other sources I got a few things around that would be nice to have some bailing wire to tie up.
