On several occasions I have had cows moving into the feild that have spooked some deer i had been overlooking in my stand,i would wrether mow a pasture for wildlife to be in,than have cows eat it down for low undergrowth.

I have had some run-ins with the least # of fence strands i could go with and cows getting into food plots.
I found that 3 very tight strands work well.Last summer a couple of cows got into my sorgum,peas,and beans and destroyed a really awesome plot because i just put up two strands.and i was left kicking myself.
