Best "fishing" I ever had was a cow that wanted to get beyond the poliwire each time I moved. The desire to be number one. One morning I was shifting the reel and she tried to jump over, got the poliwire on a leg or two so I took the opportunity to unlatch the stop on the spool and hook the reel back on the fence. The hook was set. wow, dance, bellow and prance and head back to where she was supposed to be. Got loose by herself, I had to reset a few step ins but she never tried the escape plan again.
