I see deer tracks puncturing some of the plastic already!  We have a serious deer problem which will have to be addressed.   I installed a 5 wire slant fence clear around the field using a mix of polywire and 1/2 inch polytape bought on ebay.  The ground was so hard I could barely drive in the t-posts 6 inches!  Unfortunately the field is adjacent to a deer highway that the varmints travel on to get into a nearby subdivision.
